DIY 7x5 LED scroller

Kalanda sent in this 7x5 dot matrix LED scroller based on the Attiny2313 AVR microcontroller.

It looks like a fun little project, but the part I really dug was the way the animation is programmed. The author created a simple LED Composer HTML/Javascript page that lets you visually construct the layout of the animation, its speed, and the animation style (scrolling or frame by frame animation). You simply click on the virtual LEDs, make it look the way you wish, and a textbox spits out the necessary array for you place in your program.

Here's a link to the project site, both in original form, and lovingly translated by caged typing monkeys at Google:
