StayFrosty I know what you mean about cluttered displays.
I don't have space for permanent displays - but I have created a diorama of the atmosphere processor/hive that I use for photography (I need to upgrade the lighting for that) and keep all the collections in BIG tubs (one for Queens, one for warriors, one for drones, one for hybrids, one for military humans, one for civilian humans, etc.)
That way when I get a new figure or new repaint/custom I can set it up within the diorama for photos (better than seeing my wardrobe in the background).
ps. I am planning on creating some more dioramas that can assemble/disassemble easily for storage - one will be the egg sack for the Queen, so should give support (I'm looking into options for materials) that diorama piece can then slot into the side of the existing diorama.
