Copper-generate WB Backdrop

Hey all. I recently came across this video:

And I asked about his Workbench backdrop, which is "just a copper list generated by a program called waverlauf, or something like that".  

Anyone know exactlty what app it might be? My google-fu is failing me today.

Also, anyone know if such a thing exists for 1.3?

Excellent! Thanks!
