Im actually about to make one out of some stone looking formica i have around here and maybe some branches. I like the natural look personally, but thats just me. I guess thats also why my aquariums all have natural color mixed river rock, and my largest tank all live plants and real drift wood. I think an important aspect of good pics is gettin the lighting right. If im not mistaken there is a sticky on here somewhere about how to set up the lighting.
