We got to hang with Spike Lee, LeVar Burton, Reggie Watts, Ayah Bdeir, David Gerrold, Bens Heck and Huh and Rachel Haot. We played around with Occulus Rift, some electric skateboards, a surgical robot and a few 3D scanners. Once again, however, our Insert Coin competition was arguably the highlight of the whole Expand event. Ten products competing for two big prizes, to help jumpstart their crowdfunding campaigns. Once again, the diversity of the projects was staggering -- a fact that no doubt made it all the more difficult for our panel of illustrious judges to pick just one winner. In this second of two Engadget Show Expand specials, we follow the journey of our top five finalists, MyBell, GrowCubes, Smart Power Strip, DiWire and Blink Scan. Huge congrats as always to all the semi-finalists and a big ole thanks to co-host Mark Frauenfelder and our four-judge panel.
