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.

R Tape loading error, 0:1

This shader is simulating the look of the loading sequence for a 48K ZX Spectrum. I was surprised to find I could do this all from memory. It’s amazing how much you can understand about an old 8 bit machine.

VGA Mandelbrot

This is my tribute to Fractint, a fascinating DOS program with an amazing selection of fractals.

Mostly Harmless

The iconic Cobra Mark III from Elite. I tried to simulate some of the shortcomings of 8 bit rendering with this shader.
