To be clear, this jQuery plugin was not made by @voronianski not @hakimel. The original Avgrund concept is Hakim's. I think the way this was presented is really freaking confusing.

@hakimel is Hakim El Hattab :) he's author of original idea. but @voronianski (Dmitri Voronianski) have brought this idea to plugin that everybody can use with ease

Radar is really cool, and interesting to play with:
