Hi Rob,

Thanks so much for writing. I'm sorry to hear someone gave you grief for just trying to make a nice post.

We (my partner and I) frequently see our art used without credit... while it's always nice to have our name on anything we worked on, I get that it's the internet and almost anything goes.

We do ask our friends and fans to help promote our stuff, because like many working artists, we are piecing together a living, mostly from word-of-mouth, and every little bit helps! :)

Hope that's a sufficient answer. :) thanks again for asking ...if you'd like a free poster of that wave, just shoot me an address and I'll send one out to ya.

Sincerely,
Randal
