As for the big rocks? I don't remember what it was called. I like them a lot and they are super heavy. Here's a bigger pic of them two of them - I'd like more.your substrate hurts my eyes!!! im looking at the comps and than i looked at the substrate and BAM!!!! i was like woah thats bright. and if you stare at it, it looks like its moving or something. you can like see things in the design if you look. what is that stuff?? that and the rock, it reminds me of DR.
