my clip was made only with DIY modules 
I started with my Asymmetric Studies patch to get a creepy house-like shape, then added a lot of feedback routings with the Castle VCO (synced by that same complex shape), Flipflops en advanced color mixing, and added some pulsating animation with a LFO and touch sequencer (Rene) .
The grainy stuff comes from feedbacking the Hard Key with itself (through other modules)
