I'm not sure where I first encountered Looney pyramids, but I've been looking for an opportunity to get into them ever since. Eventually I got a copy of Homeworlds + Ice Duo using a coupon I won in a charity auction, which opened up a whole ton of games, though I did have to make most of the boards for them (yay for my laminator). Later I upgraded to Pyramid Arcade + 2x Nomids.
I made Bag of Ice and Hivemind.
