curious popup

i was surfing the web today and a popup came long. i admit i found it curious and clicked to check it out. so there appearantly is a whole web page dedicated to different sex positions. they have over 100 3D animated sex positions (so its not dirty, purely eduacational):p and fun!

the positions are devided into different "families" (and i didn't even know they were names for all of them...), which leads us to the question of the day:
how many positions have you tried out? (if anyone replies to this they are very cool).
