The Blasterman Universe is my most worked-on creation, about the Andromeda Galaxy in the mid-41st century.
To be honest, I don't actively build Lego creations that much anymore. I had to move my bins of Lego upstairs into an area where there's not much building space (I suppose I could clean off my desk...) because of the treadmill we bought. It's a great treadmill though!
