I tried one of my trusty WEB searches at Jay J's Favorite WEB Search Engine, and entered +"indoor fountain" & +"home" ('+' and '-' and '&' included), and pressed the Search button. I got a ton of hits on Indoor Fountains. I never thought there was such a market for them but I guess there is with so many related hits.
Good luck sifting though all the 'hits' that apply, Steve. My best to ya and hope this helps.
