Wow, that sounds like a really great project. A viewing window into a pond from your man cave. Sitting there with a few friends sipping on some adult beverages, watching your local sports team on the big screen TV. All your fishes gathering on the other side looking in at you. What's not to like? Hey, was that your brother-in-law that just swam past... with a speargun in hand? LOL, what could possibly go wrong?
