actually, after reading this thread i didnt have TOO many ideas on my own
so i asked a friend with no robotics affiliation to give his best deliberation
"Just be careful about the stock market, with jello, gerbils, and K'nex blocks."
"
stock market has ups and downs
jello would slow you down
gerbils are frantic and can do anything spontaneously
well for k'nex you have to build stuff really fast
"
hmmmmmm...
it actually makes sense to me!
