Made for rendering in cycles. It has some weird shader errors happening with noise appearing on transparent materials. Colors of the middle flowing things can easily be changed in the material node setup. The background environment HDRi texture is an enhanced version of the free "Ditch River" from sIBL Archive (http://www.hdrlabs.com/sibl/archive.html)
