Two tech tools

Both from PurplePawn.com.

Not cool:  Yoyn - There is nothing in this demo that shows me how a game can be played better on this platform than with cardboard pieces.  Rolling the die to roll a virtual die is strangely cool, but also pointless.  There has to be a better way to use all this technology.  And the background music for the video is maddening.

Cool: Lego Robot Chess - ironically, still mostly pointless, but makes up for it in style points.  The pathfinding algorithms must have been a bear to write.  My favorite parts:  1) The pieces going diagonal and backing out of the way to allow a piece to move diagonally through them; 2) the reveal, midway through, of the scale of the board, and 3) the animated parts of the mega-pieces, like the knight's rearing horse with animated forelegs, and the queen thumping her checkmate challenge at the end.

Both of these have an insanely low effort-to-utility ratio, but the lego chess is cool on a number of levels, maybe even for this low ratio.
