Joke/experimental wad I can't find anywhere

[invictius]

It was a megawad, one of the early levels had you on a gray flat shaped like a plane, with scrolling etc, like you were travelling. I think you had to avoid falling off, or had to dodge fireballs or something. There were many other unusual/experimental maps. I downloaded it in the last year or so but don't know if it was made long before that.

Mandrill Ass Project had many unusual/experimental levels and one of them involved jumping over planes, too.
