Road to Infinity - Portals

My submission for Bad Normals's "Road to Infinity" Render Challenge. I'm really happy with how it turned out, even though I know it could be polished in some places. My only enemy was a short deadline made and extremely long render time, even with render farms - glass fractals with refraction are a pain to render. Either way, I had a lot of fun making this.

Rendered in Cycles.
