Hi! Here is .tox file with water ripple effect made with GLSL. Code is based on this shader, but I did some changes and leave a comments for you. You can also read theory behind algorithm here.
Broken mirror and distorted lenses effect with camera displacement trick. Made in TouchDesigner with basic level GLSL code, so no previous GLSL knowledge is required.
It is pretty common to be on a last-minute gig and need to drum up a bunch of visual effects and looks to fill time during your event or performance or similar. Building these yourself may be the ideal option, but it probably isn’t realistic given the budget and amount of time before the event.
