Several years ago I used a pinball playfield as a centerpiece for a coffee table:
Am almost done building another one for Super!BitCon. The image below is a dry fit of the trim. Had to mark it all to start cutting the slots for the biscuit joints and what-not. The top frame that will hold the glass can be seen just off to the left.
Then I've also made several arcade marquee light boxes that I've sold at past game conventions. This photo was taken at OVGE 2012 (started off with seven). I still have a few that I'll be bringing out to S!BC.
My mother has recently resurrected a project I began about five years ago that I dubbed "pixel pillows." She's been going to town sewing (much better than I can) and will have a number of them at S!BC (assuming I don't snag a few for my couch first
). The space invader is the most recent one in the works.
