How can I find out more about hip hop exercises?

Not sure if this will answer your question, but Beachbody the group that has produced P90X along with many other home workout programs also offers "Hip Hop Abs" home workouts. 

Here's the link for more information http://www.beachbody.com/product/fitness_programs/hip_hop_abs.do?code=SEMB_GOOGLE_HHA&extcmp=e00d4d9a96635c90&ef_id=jUVNeMfpdy4AAMui:20110310124529:s

I don't have any financial interest in this program and haven't evaluated it for it's effectiveness or safety, however if you feel the program aligns with something that you would enjoy....I say do it!  If you like something and it's fun you'll be more apt to participate and stick with it.

Hope this helps.
