Pretty neat, I remember I looked at that article and had a lot of trouble trying to understand what it was saying and implement it myself, so props for doing it.
I noticed some problems when using the .love you posted that, like the light not behaving in a way you might expect it to. I think it would be really cool if you continued to work on it and make it something fully fleshed out, I would love to be able to use a light library that performs well and is easy to use.
Good implement. And thanks for updates. I just had some bugs with functions (perhaps this is my personal problem), but now everything seems to be ok. I would like to know where I can find similar tutorials or materials on this topic?
