You may recall a SymbOS image in advertisement style in 2007. That particular image was the winning entry of MSXart'07, a competition organized by the
Passion MSX website. If you intended to compete with that challenge, but couldn't make it in time, you'll get a new chance: MSXart'08 has just been announced! As with previous editions, the idea is to create an MSX-themed wallpaper. Eventually a calender of the 12 best entries will be created and the creator of the best entry wins such a calender. The deadline for this competition is Sunday 12 October 2008, may the pixels be with you!
