I think tons of HN tech people are into LEGO. After they gathered 10,000 votes and still declined to do a JWST telescope TWICE, I personally decided to have some fun with it on my own.
Yeah - technical people in general - it was a great introduction to following instructions and creativity all-in-one. (I would build every kit first with the instructions, then tear them apart and put the bricks in the "big" (actually very tiny) box, and from then on, build my own creations - no models sitting on shelves for me - this still happens to-this-day, but now I build with my grandkids)

Plan to Kickstart it early next year...
