## Game of Life Based Clock

Check out this Game of Life Based clock made with a 16×32 RGB LED matrix, via hackaday:

[Matthews] needed a good present to give to his brother-in-law, who just so happens to be a mathematician and programmer. He wanted something functional but equally geeky at the same time, so he decided to try his hand at making a Game of Life style clock.

He was originally inspired by a Game of Life Clock we shared a few months ago, but with a few improvements. First, he wanted a much bigger playing field, so he found a 16×32 RGB LED matrix. Second, he wanted the time to always be visible so it actually works as a functional clock.

## Repeating Game of Life Pattern on 8×8 Bicolor LED Matrix

Via blog.arduino.cc:

I recently got one of those 8×8 LED matrices and I was playing with some Game of Life patterns when I found this pretty repeating pattern. I found it by starting with some random patterns. If you look closely you can see the pattern becoming a mirrored version of itself halfway through. Apparently the pattern doesn’t repeat like this on an infinite grid but on this wrapping 8×8 grid it does

Check out Remco Veldkamp’s source code here!

Adafruit Bicolor LED Square Pixel Matrix with I2C Backpack – What’s better than a single LED? Lots of LEDs! A fun way to make a small colorful display is to use a 1.2″ Bi-color 8×8 LED Matrix. Matrices like these are ‘multiplexed’ – so to control all the 128 LEDs you need 24 pins. That’s a lot of pins, and there are driver chips like the MAX7219 that can help control a matrix for you but there’s a lot of wiring to set up and they take up a ton of space. (read more)

## Game of life DIY by Manuel Montoya Aguirre

Game of life DIY by Manuel Montoya Aguirre:

Ever since I discovered John Conway’s “Game of life” I have been obsessed about the interesting patterns of such a simple algorithm. A few weeks ago I decided to design a USB toy capable of running the game of life on a tiny 8×8 LED Matrix. This is what I came up with.

Since most of the stuff I used is easy to find and not very expensive, I decided to share the diagrams and the code so you can build your own Game of Life. The Arduino code is available here. I got the parts from adafruit for \$17 + shipping (I didn’t buy an Arduino)

After wiring it, your project should look like this

Upload the Arduino sketch and repeat the following for next 5 hours: Stare, push button, stare, push button, stare, push button.

The cool thing about this project is that you can pause the evolution by pushing the rotary encoder. Then you can go through each step (“tick” for those who know their automaton) until you find a stable universe or extinction. Currently there is no backwards evolution but I am planning to implement it on the next update using memory to store the last 10 Universes.

## Beyond the Game of Life

Beyond the Game of Life. Jude writes -

When I first came across the mathematical simulation John Conway’s Game of Life I played with it for hours, constructing all sorts of weird and wonderful creations that seemed to mimic nature.  The Game of Life was the Minecraft of my generation; an elegant,  2D, monochrome, zero-player, non-social version of it.  From such simple rules, emerged what looked like “life”: self replicating structures that interacted with the chaos of the canvas. Over the last few years, I’ve been thinking of the variations of the Game of Life and will explore them in the post.

Interesting ideas!

Conway’s Game of Life Kit – v1.3

## Seattle Science Festival

Seattle Science Festival. James writes -

I was able to solder up and complete the Game of Life kits in time for display at the IEEE’s booth at the Seattle Science Fair. The event was a success, with the goal to attract children and the young at heart to see something cool and ask questions regarding the world of electronics. Two parents asked where we purchased the kits and I gave them the Adafuit’s name and website.

## Life in Life: Conway’s Game of Life Self-Similarity

Call it Monday Morning AutoMata. This great simulation of Conway’s Game of Life which runs a smaller game inside itself. phlipping writes:

A video of Conway’s Game of Life, emulated in Conway’s Game of Life.

Inspired by this video: http://www.youtube.com/watch?v=QtJ77qsLrpw I made a similar video, but with the speed and scale varying smoothly over time, rather than in discrete jumps as the original video did.

The life simulator used is Golly – http://golly.sourceforge.net/ which has a built-in script to generate these metapixel grids (select a pattern, and choose “metafier.py” from the scripts list). For more information about the metapixel pattern, see http://otcametapixel.blogspot.com/

The actual video is exported from Golly using a custom Python script: http://pastebin.com/8vVGCgKE (since Golly built-in only supports rendering the view with a scale which is a power of 2, for performance reasons – this is not a particularly well-optimised or fast script to run).

The audio track is a Shepard Tone: http://en.wikipedia.org/wiki/Shepard_tone
This is also generated by a Python script: http://pastebin.com/vxVeNtWc

I can’t help but think how cool this would be projected (or installed) on the side of a building opposite a waterfront or canal.

editor’s note: original quote contained a bad link to the Shepard Tone WP page, so I fixed it. All other quote content is directly from the YouTube video.

## Interactive Game of Life Kit

Two years ago we designed an interactive exhibit of Conway’s Game of Life for the San Jose Museum of Art. The hardware that we used for that project eventually became the basis for our Octolively interactive LED kits.

We’ve recently had occasion to revisit our Game of Life project, and to build an all-new version of the museum exhibit. Along the way, we’ve rewritten the firmware from scratch and added a number of features. And today we’re pleased to announce the result: our new Interactive Game of Life Kit.

## Nice Game of Life array!

Although I know better than to call any project really ‘finished’, I’ve got my Game of Life array all set up, in a nice frame / enclosure, and with a silly complicated over-engineered way to turn it on and off by remote control.

Not the TV remote control that I had done before… that worked ok was imprecise, didn’t allow for finite control, and was succeptible to interference (spuriously turning on all the time actually.)

What I’ve got is 20 Game of Life kits assembled into a 5 x 4 array. This is roughly 20″ x 16″ in size. It’s mounted inside a wooden enclosure / frame, with a dark green acrylic front panel. The entire display is mounted on a wall in my livingroom.

In addition to the boards all being connected together normally, I’ve tied all their control buttons together so a single signal can turn them all on or off at once. This switching is handled by a PN2222 transistor. The transistor is driven by an Arduino Pro Mini, which in turn receives its commands through an XBee.

The commands originate from my DIY Thermostat across the room, which is now also XBee-equipped, and has some additional code that tells it when to turn the Game of Life on and off. The timing is based on the day of week and time of day, essentially meaning that while I’m home the GoL will be running, and while I’m at work or asleep it will be off.

There’s some code as well which lets me send the on/off commands through the network, which the thermostat relays to the Game of Life. And finally, a push-button on the thermostat can control the Game of Life, should I need/want to manually operate it.

I’ve done a more detailed write-up of the whole thing on my blog.

## 5×5 Game of Life Wall Art

The IEEE Student Chapter at Seattle University created this terrific 5×5 Game of Life display to hang on the wall. aerohoff writes:

Fall 2009, as a senior at Seattle University, I was disapointed with the lack of soldering in my electrical engineering courses. As the co-chair of the IEEE student chapter, I organized a soldering workshop where each student got to solder together one Game of Life board. We connected all the boards together on a display board that will hopefully get put up on a wall somewhere. We got 25 of them together and into a 5×5 grid. The paper on the right explains the rules of Conway’s Game of Life and explains how the board came to be.

Beautiful work!

## Game of Life kit reviewed…

Nice review! Tronixstuff writes

This month we’re looking at the Game of Life kit from adafruit industries, the team that brought us the SIM reader and other fascinating things. This kit is simple to construct, yet interesting to watch in operation, almost mesmerising. If you love blinking LEDs, this is the kit for you. Furthermore, it is very easy to construct which makes it a great kit for someone who is learning to solder.

## EKG-controlled Game of Life hoodie

Joe Saavedra writes-

The concept is a wearable version of Conway’s Game of Life, that is controlled by the current state of your life. Essentially, a wearable extension of your heart, externalized in the form of Conway’s Life. A custom circuit includes an infrared EKG monitor that resets the Game each time a heartbeat is detected. Heartbeat data is analyzed by a hackduino which resets an ATMega48 chip, part of Adafruit’s kit controlling Life, which is embedded in the chest of a hoodie. Conductive thread is used to connect the 16 LED matrix to the circuit board which is kept in a pocket towards the bottom of the hoodie.
