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
