Neat looking, but not much to observe. I find observation hives with parallel frames pretty useless. You'll never see the queen or brood, just bees wondering around and perhaps storing honey on those outer frames. If your going to do an observation hive, go single frame wide so you can see the interesting stuff. I have a 4-frame deep in our house, and my son is designing a 5-frame observation hive for our library as his eagle project. I'll be sharing the details once he has things moving along......
