A 4-part OVA created by Studio Pierrot.  It was 
actually first ever DVD-only release by Bandai 
USA in the United States, I believe.  So you can 
pick it up at pretty much any anime DVD retailer.

And yes, there are cels from this show, although 
most folks can't recognize them.  If you would 
like help locating some, let me know.
