A peek of the current state of 35 hours’ painstaking labor, all by hand with some help from circle and line tools. It’s a fusion-powered laser battlestar, radiators and coolant vents lit up like a furnace. The big blue surface is the main mirror, which focuses the beam onto the target. This has been languishing for a while. Maybe I'll finish it some day.

4GW laser battlestar/destroyer. Scale information: It's probably about 100m wide, 250m long? Somewhere in that range. The engravings in its hull paneling are maintenance tracks, ladders, and access points for repair robots and crew, so those are at least 1m wide.
