Impressive 32 LED globe

Moving LED displays are popular projects. But this seems really interesting as it uses pretty simple but effective solution. It is driven by ATtiny13 microcontroller that sends signals to LEDs via 4 shift registers.

Microcontroller simply stores globe image in 32×70 bit array then sends column signals while motor is spinning. Assembly of project looks really neat and well documented, just in Russian language. So use online translator.
