Soft-core porno with a funky 70's soundtrack (all original, as far as I can tell). It's light-hearted, sometimes bizarre, and it fails to be pornographic only because its gonzo pop-art style is so distracting. Gonzo pop-art to the point that you could probably play it in the background at a party and keep people more amused and entertained than offended. (The film opens with a film crew member staring away into space and the first line of the movie is "Turn around schmuck, we're rolling!" Corny gags like that are common.)
The psychedelic orgy at the end is fantastic and not to be missed. The underlying message is that Life is beautiful, sex is fun, and people are weird-looking but joyous.
