Microsoft TouchWall can inexpensively turn any flat surface into Bill Gates will demo a new multi-touch computer and interface today called TouchWall at the Microsoft CEO Summit in Redmond. TouchWall refers to the touch screen hardware setup itself; the corresponding software to run TouchWall, which is built on a standard version of Vista, is called Plex. TouchWall and Plex are superficially similar to Microsoft Surface, a multi-touch table computer that was introduced in 2007 and which recently became commercially available in select AT&T stores. In a demo yesterday, though, Microsoft Office Labs GM Chris Pratley and Director of Envisioning Ian Sands said that the two products are completely different.

Origami Tessellations

Origami Tessellations To continue the origami how-to video fun, here’s a new one from my partner Ioana Stoian showing how to fold a cute origami cat designed by Roberto Gretter and Ioana during the Polish origami convention earlier this year. What a fun little cat! And it’s based on 60 degree angles, which for geometers like me is particularly satisfying… I saw this fantastic little 4:30 minute documentary on Bobby Jaber, a retired chemistry teacher who has spent the last 20 years working with porcelain to represent geometric shapes and solids. It’s beautiful artwork and well worth seeing. It reminds me a lot of Shuzo Fujimoto, a Japanese chemistry teacher who decided to fold paper to help represent chemical structures for his students; he was one of the first origami tessellation masters, and his explorations became the basis for most of what exists in the origami tessellation world these days.
