Somebody built a whole alternate-history wargame universe on top of LEGO, gave it away, and grew a community that writes fiction and draws art for it. The designer's point that bricks are the perfect prototyping medium will ring true to anyone who has ever hacked something together. The included squadron instructions are a nice touch.

A builder took LEGO's Monet set and reworked it into a moody night-time palette, then wrote up which part swaps worked and which colours turned out to be liars next to their neighbours. It is a good look at colour theory done in plastic, with a comment from the set's designer about how many bridge colours they tried.

Two of this feed's favourite things in one small build: a speeder bike wearing a tyrannosaur as a body kit. It is compact enough to actually build this weekend, and the write-up explains the pipe-frame trick underneath. The final jaw detail left out of the instructions is the kind of nerdy footnote worth reading for.
