Quoting Paul Graham "ideas are worthless" (ref: http://www.paulgraham.com/ideas.html)

I would suggest cracking out a prototype and go from there - "ideas are 1% inspiration and 99% perspiration".

[Wadsworth]

I ended up building the prototype this morning (a bit of insomnia). Now I've got this cool little demo (fully functional) running on my iphone--- now what?
