VeinViewer.

It's vampiric technology!

That totally has me geekin' and freakin'! That blows black lights right out of the water...

yeah, that's what i thought too. then i watched their video and saw it's more like shining a light on your skin. awesome technology.

as for the halloween costume. maybe the technology will become available one day to be mass marketed... then you could host a naked disco with vein-viewer strobe lights. (or at least make it hot enough on the dance floor that people will be scantily clad with lots of veins showing.)

See for a second there I though it was some nifty little patch you put on your skin - so then I thought.. ooh.. get a bunch and put them all over and you'll have one helluva Halloween costume! But alas it is a machine. Still very cool!
