Sorry, Milhouse. Here it is (hopefully): http://sprunge.us/AZXe

Thanks. What version of the screensaver.shadertoy add-on are you using? I suspect the version in the repo may be incompatible, and the last version I uploaded on 1 April certainly is, so it could just be crashing due to some binary incompatibility.

I've uploaded a new version of screensaver.shadertoy here - please install this new #1128 version and see if it works any better.

If it continues to crash, install this debug-enabled build #1128y as this will provide a more informative crashlog.

If you also plan on using visualization.shadertoy be aware that this add-on crashes (crashlog) quite regularly and as there's no way to report issues to the developer my advice is just don't use it.

Looks like I had v1.0.10 installed. I tried the new version and it triggers the same instant crashes.

I don't have plans to actually use this screensaver, especially given your advice, but after I get that debug build downloaded I'll post a crashlog and whatever else I can to help.
