Ballista bow Printer Friendly Version
This idea is for a steel torsion spring powered 'ballista' (ancient roman war machine that resembles a crossbow) which fires ballbearings. It could be used for hunting and with such durable ammunition it would be more economical than bows and arrows or firearms. Also would be great fun to shoot at gongs!
Reward: I'd like to shoot one

Tennis glow-dome, or zen-dome Printer Friendly Version
Hardcourt, clay, grass... now introducing the glow-dome. Basically it's a tennis court 'bubble' where the players compete in total darkness. Visual elements such as ball, net, court-lines, tennis apparel (head bands, shoes, etc..) and racquets will glow in the dark. Everything else is not visible. This will offer players a new 'experience' not unlike a vector-based videogame reminiscent of TRON + the added clustophobic element. At this stage I envisage only player participation, as I do not know how to incorporate lines people, umpire, spectators and maintain this 'bubble' condition (everyone would have to be outside the bubble looking in. Plus the type of glazing required to block out total light from the outside).
Reward: watching the russian female players play in their glow-in-the-dark underwear will suffice.
