Votes are in. I calculated it that 1=0, 2=1, and 3=2, by sum.

Smart Desk: 3
CC430 Platform: 11
Xylophone Blocks: 14
Color Explorer: 13
Physical Sensor Array: 16

(individual votes after the break)

Smart Desk
1 1 1 2 1 1 1 1 2 2
= 2
(Seems too broad / ambitious for time frame)
(Not enough time to be innovative. Would end up half baked likely, with only 6 weeks)

CC430 Platform
2 3 1 2 2 1 2 2 3 3
= 9
(Seems cool, but not really seeing the direct educational aspect)
lolwut?!

Xylophone Blocks
3 2 1 2 3 2 3 3 3 2
= 13
(Music is fun, and I can see some innovative use cases emerge)
( Do want for LATER though…I have ideas… to hell with it, this is cool too)

Color Explorer
3 3 1 2 1 2 3 3 2 3
= 11

Physical Sensor Array
2 2 3 3 2 3 3 2 3 3
= 14
(Like it, but don’t see the innovation aspect for competition)
