Wow.. that thing is cool.. but no I don't have that one. It's much simpler. Something like the leg portion of this http://heavenlyhomemakers.com/great-lunch-idea-black-bean-salsa

Like the leg portion of... black bean salsa? It looks delicious, but I think you're going a little off topic lol I think you attached the wrong link.

Alright, still going off of your description, the only other machine I can think of that fits that description is the Leg Curl which is what I do. It is an isolation exercise for the hamstrings mostly, although it works the glutes a little bit.
   
That would not suffice at all for working out your glutes because, as I said, it is an isolation exercise for the hamstrings.
