Sonic and Knuckles 3D fan video is all sorts of rad

Before you get your hopes too high, we feel morally compelled to inform you that the video posted after the jump, a purported gameplay clip from Sonic and Knuckles 3D, isn't culled from any upcoming licensed game. In fact, it's not even from a fan-made game -- rather, it's just a pre-rendered video from a skilled 3D artist and YouTube user by the username of BlobVanDam.

Spin-dash past the jump if you want to see the Mushroom Hill Zone Act 2 that never-will-be. Actually, that's a pretty defeatist attitude to adopt. We're sure that someday, in the fullness of time, this delightful vision will be realized. Until then: Sonic 4!
