There are two incredible developments in the interactive tables arena, the muti-touch table by Jef Han and the touch table by Applied Minds. So, whats next?... A freakin dynamic 3D version of one!!! Yes, like the one in the X-men movie. Xenotran has developed a Dynamic Sand Table (DST) that can produce accurate topographic models in under 3 minutes. It's basically a table with a bunch of needles that retract or extrude upwards to represent the projected terrain. Watching this table work is awesome!
