So i just bought this guide and to my surprise they actually had a little section on ats's . They even had a video with a guy running a waterfall.

Interesting to note that:

1: Mark callahan didn't bash or promote them. He only said that diy was not his thing so he stays away from them.

2: He noted that there were none comercially available to purchase.

SM get a hold of this dude . I see a huge possibility to reach a mass market for you here. Or anyone else for that matter. Hell if we could get floyd to build him an l.e.d box I'm sure he would try it out.
