Sometime in the late 1990s early 2000s there the website for bomb hip-hop - which was an amazing indie hip-hop production group - had this really great flash demo that I think is gone from the web forever.

Basically just a looped beat and you could play with different elements that made scratch or other hip hop sounds- might have even been what amounts to an interactive link box

If I had any money I’d pay if someone could find it again but alas I think it’s gone forever!
