All the stuff I plan to do and random ideas that I might get around to one day

Distributed AJAX raytracing

I found this Raytracer written in JavaScript but it takes too long for any reasonable resolution. So, I plan to fix that by parceling out small parts of the render to different computers and gradually build up the image from the data they send back.

Instead of putting adverts on a website you could put some JavaScript that does distributed computing, using AJAX to return the results, the owner of the website gets paid depending on how many calculations their visitors do. The advantage to the visitors is they don’t have to look at any adverts.
