Not a software developer, but I am a carpenter and had built, for our own use, various storage boxes, shelves, and even 2 high chairs for my kids over the years. A fun one is when my older son injured his left ankle at the playground last year, I built a makeshift knee scooter out of some scrap wood and 4 all direction wheels. Both my sons are still using it as a scooter to speed around the house to this day. My daughter never even touched that thing. I guess boys will be boys.
