The LED bed uses Red, Green, and Blue LEDs, it works the same way asr TV or computer monitor works, Red+Green=Yellow, Red+Blue=Purple. The Maker has a how-to, photos and a kit if you don’t care to build your own. Link.

I’m going to try to round up some Science listening or watching each week- Science Friday: Self-Replicating Robots / Science of Sexual Abuse & Stem Cell Spinal Cord Treatment / Science and Technology in the UK. The power chat with Sir David King was really great, you can conserve resources and grow economies it seems. Subscribe to the Podcast here. Eyes of Nye has Addiction and Antibiotics as the two episodes that came over my TV recorder. It would be great to get a non-Flash version of the eyesofnye site, RSS feeds and an easy way to link to the content on the site- there’s great stuff hidden in there. Link.

Growing up as an only child, I spent a lot of time with an 8-track playing “robot” called 2XL. You’d get tapes and he’d ask you questions, to answer you’d press a button and then depending what you pressed it would play another portion of a track. It was pretty cool at the time and the Science tape was my favorite. Someone has made a Flash based one with many of the tapes you can try out and play. Memories! Link.

MSNBC’s Gary Krakow got the DIY bug and made some holograms using the Litholo hologram kit. The article explains what holograms are, how they’re made and special “instant hologram film” used to make the home versions. Usually holograms require that there be no motion at all, but the home kit from Litholo gets around that and from what the article says, produces great results! Link.
