Post your psychedelic art

I've recently become fascinated with psychedelic art, and I want to start making designs similar to what I've seen. Post yours, inspire me.

 

sorry for low quality, just some sketches I did a while back.

 

I love that cow one!! O_O

 

The middle one is great, I've seen it somewhere before.....can't remember where though.

 

Not sure if you would consider it psychedelic but it is art.

 

It's the cover of Terry Gilliam's "Brazil."
