It's a cool little retro camera, there's actually a free Android app that emulates the entire crappiness of the PXL-2000 experience, so you can try it firsthand :-) App can record GIF sequences and snap photos

(I'm the developer of the app and it emulates different oldshool digital cameras like PXL-2000 and Gameboy Camera, its really free and open source, pull requests most welcome)
