Via 2ModernDesign comes the link to this idea for a geeky x-mas present: Woodpixel – Create your own pixel art… from wood. I would say this qualifies as a gizmo type present.

If you suck at Photoshop, there’s hope on the horizon. Now you can create graphic art without stepping foot near a computer. If you’re a retro gamer, you’ll appreciate this even more…
