Does not this look like an intro once made by Hotline? Perhaps it was the other way around, but when reading about the sprite glitch I do not think so. The intros by Silver Surfer of Hotline used to be original and good.
Nice FBR intro by Ironfist. Music really suits this gem, but one thing that always annoyed me was that the sprite sinus doesnt return to the starting position...so theres a small jump "bug" of the FBR sprites.
