Ugh, I really should trim the start of this vid, sorry. Action starts around 0:19

Nice little program. Did it take a long time?

No assembling it took longer than writing the code.
It's based on a Parallax Propeller chip which uses a pretty high level language called "Spin." The drivers for the LCD and for the PCA9555 (IO expander driving the LEDs) were made by tweaking code found on the Parallax website.
Once the drivers were in place, making the animation was simple, like writing scripts in Python or something. write(text, line), clear(), delay(time), etc. I made a couple functions to help with repetitive animations.
