This LED Bar is almost open for Business

We received an original letter in the shape of a scrolling LED marquee. This is what it says in French:
“Ideal observing distance 3 m, in full darkness. Hello Elektor! Thank you for everything you have taught me about electronics! This project is open source and may be published and improved. 180 LEDs controlled by a single PIC 18F46K22 clocked at 64 MHz, the program is written in C. A gift for you! Best regards, Joël Huser, Switzerland”
