# The Business Card Ray Tracer (Not Working) This is a more readable adaptation of Andrew "aek" Kensler's original 1337-size ray tracer written in plan 9 C. Sadly it doesn't work yet. I'll have to go through it more thoroughly to find out the quirkyness that makes it generate a smaller, wrong file. You can read an updated version of his [here](http://eastfarthing.com/blog/2016-01-12-card/). I also recommend you take a look at Paul Heckbert's “A Minimal Ray Tracer”, Graphics Gems IV.
