Exchange value aggregation feeds

[bosshyip]

So I'm looking at doing some basic little programming projects as I've finally found something with a small problem domain that I think I can solve.

I've seen some links to some bitcoin exchange value aggregators, that take the USD value from various exchanges and cut them together in JSON feeds.

Can anyone link me to this?  I can't remember anything about the threads other than these links, and I can't even come up with proper search terms to find them.

I want to write a little python program that grabs this feed and shows it in a nice little program.  That or a little android program that does it.  Either way it should be modestly rewarding and useful.

Thanks!
