since you're still looking for other ideas, I gotta mention some software domain stuff:
  -- SonicCouture stuff including GeoSonics and others
  -- some of the Native Instrument lineup like ScannerXT, Form and others
  -- a lot of the GlitchMachines lineup particularly for "tech" sounding textures
  -- Spitfire Audio BT Phobos
  -- or any sufficiently wierd sample set (like Zero-G Ian Boddy Odyssey) run through granular and other mangling
  
  There's SO much in software, it's really worth a good look.  And so much on holiday sale presently.  Some modest $s would get you a bunch of the relevant software.
  
  AND assuming you have a DAW to modular setup (like Expert Sleepers unit) you could pass your DAW texture audio into modular for additional mangling

I would like to be able to do it in the eurorack.what i do now is load my own samples inro the 2hp play module.
A module that looks awesome for textures is the addac 112
