Looks like a good idea to me. I do like "The Speculation Game" idea and vouch in to add a reward to the winner. I can give out like BTC 0.002 for the game  
I will participate in it as well. May be we can get a donation from other members as well and create a wallet whose private key you or an escrow can hold and give it to the winner at the end of the day.

I have another Idea. The person with the coolest avatar (should dedicate India and bitcoin/bitcointalk) will get a little reward.
The person should wear that avatar for that whole day. Again, I know we don't have enough funds but we can surely loose out our wallets to give out a little for the community.
I don't know about the others but I can surely do it. Besides that, if you take it from the community, you give it to the community.
