LED Pulse Network: Part 1

Today I finally got around to starting a new project: making a ring network of three Arduino-compatible boards so they can talk to each other and pass around a "pulse" of light that will be displayed on a large number of LEDs.

Today I just set up the LEDs and made a rough sketch of the LED animation. Here's a pic of the setup:

I would have made an actual ring shape of LEDs, but considering that my other breadboards are currently in use, it was easiest to just wire them in rows. 

Currently, each device is its own separate circuit. Soon that will change, I will connect them together soon.

In the meantime, here's a video of the lights in action:
