I'd prefer a Commodore PET / Apple II (black/green, with chunky fonts) or Commodore 64 (navy/sky blue border) theme over a VIC-20. VIC-20 really had nothing much to speak of on its screen, just gigantic characters. Hmm, but that gets me thinking... retro themes... old b/w Mac? Win 3.11 (Mosaic browser icon! Yeah!)? Palm? What about making a WinCE theme? <evil laugh>
