comparation of ideas

so I'm comparing the two main idea that I like.
One: Interactive dancefloor
vs
Two: Flash Choir

benifits of the flash choir: it is an unplifitng and fun project, which brings music especially classical music direct to people. which is something I really want to do. the monetary cost is quite low to implement this, and doesn't require the development of technology. it is something i could actually do.

Benifits of the intereactive dancefloor: it is a fun and innovative peice of technology (though it utalises current technology), which could bring a whole new dimension to clubs, or just be a fun experiance as demonstrations. it has the capacity to create profite. it brings the creation of music to a public colaborative level.

Downsides of Flash Choir: it has no capacity for profit, requires a lot of skilled individuals, to give their servises for free.

Downsides of the intereactive dancefloor: it requires the tweaking of current techonology, which could be expensive. it would have quite large setup costs. it would be difficult to create an effective and easy interface.
