Author here -- I also just published a new post on ray marching, which you might find interesting if you find this post interesting: http://jamie-wong.com/2016/07/15/ray-marching-signed-distanc...

My luck on HN has been not so great. All in all, I think my posts have reached the front page ~5 times, only 1 of which I submitted. But oh well! Glad they get there somehow and people like them!
