These are some of the first few Shadertoy shaders I made. They are quite old now and some are simple compared to newer shaders on the site but I still think they are quite fun and interesting. Coffee and Tablet Shadertoy had video streaming quite early and I wanted to try displaying the video on a reflective screen. I thought a tablet would be quite an easy thing to model with Signed Distance Fields.

Retro I made a number of retro themed shaders on Shadertoy. I like how silly running something retro-looking on a GPU in a web browser is. Teletext This shader is simulating the old analogue TV Teletext system in a couple of shaders. The font is the same as the BBC Micro in Mode 7. Click play then click on the shader and type a page number. The gallery images on page 300 are by @horsenburger.

This is a compilation of some of the optical illusions and perceptual effects I have made in Shadertoy. Warning - flashing images. Some of these shaders involve flashing images. If you are at risk of a seizure due to photosensitive epilepsy or other conditions, don’t click play, navigate away. Many of these effects are based on the fantastic work of Akiyoshi Kitaoka @AkiyoshiKitaoka. Click the Title of each shader to view the shader in Shadertoy.
