I got this idea while seeing [this amazing demo](https://dl.dropboxusercontent.com/u/1526334/yrdcExtra/rayCastingSoftShadows/index.html) by @yadurajiv ([Github repo here](https://github.com/yadurajiv/Ray-Casting-Soft-Shadows)). It's an AS3 implementation of ray casting using soft shadows. It would be outstanding to have something like that in Flixel, as a plugin or a core feature.
