Sifteo vs. Scrabble Flash

Scott Kirsner tweets:

"Invented at MIT, Sifteo cubes (tiny displays that talk to each other) are almost ready: http://bit.ly/eXsCQU / http://bit.ly/ehhZ1Q"

Sifteo cubes are similar (except much more expensive and presumably programmable) to Scrabble Flash, that have been around since last year. Interesting.
