Remember our Insert Coin Competition? Voting remains open through tomorrow at 5:40PM PT, and our five finalists are demoing their projects on stage today. We posted hands-ons with each of the projects earlier today, so you don't need to tune in to snag a closer look. If you're looking for a quick recap, however, this is the place to be.
