28 Apr 2015 : Updated Web Apps #
With the recent server upgrade some of my Web Apps went awry. This morning I updated the Mandelbrot Explorer and BotStop apps so they're back up and running. This means all of the kinks following the regression to 2006 should now be ironed out. Relief!

17 Apr 2015 : Back from 2006 #
Yesterday an unexpected server upgrade caused my website to drop back to what it looked like in 2006, which was more than a little disconcerting. After a bit of panic today, and with the help of my hosting provider we've now got the site back to the future again and into its 2015 state. Phew!

1 Apr 2015 : Shadertoy API testing #
There's now a page where you can test the shaders from Shadertoy.com with shaderback.js. Only shaders not reliant on channel inputs will work, so you may need to click through a few before finding one that renders correctly.

21 Mar 2015 : Shadertoy to shaderback #
It turns out many of the shaders on Shadertoy (at least those not using channel inputs) can be used by shaderback.js with surprisingly little conversion. Take a look at this really rather amazing example by Inigo Quilez.
