BigFug's glitch and feedback FFGL effects are kind of nice: https://github.com/bigfug/Free...

Yes, the TT GLSL Shaders are good: https://troikatronix.com/add-ons/tt-glsl-shaders-for-isadora-2-3/

As are the IDLab GLSL Shaders you mentioned: https://community.troikatronix.com/topic/6474/some-new-glsl-effects?_=1713797436727

I'd suggest checking out the Rutt Etra actor.

You might be able to do fun things with this by inserting images into the chain somewhere: https://community.troikatronix.com/topic/5829/if-you-haven-t-tried-the-stage-background-actor-you-should?_=1713797138076

Playing with Virtual Stages and feedback loops can also be fun (I think I did it in some Scenes in this file: https://troikatronix.com/add-ons/mouse-control-of-3d-particles/)

You could also make some interesting alpha masks for your images: https://troikatronix.com/add-ons/tutorial-alpha-mask/

Best wishes,

lots of the IDLab and TT GLSL code works nicely with images. my favourite shader to build into VJ patches is the TT Grid Warp, connected to Sound Level Watcher - and Control Watcher for some live knob-twiddling.
