always wanted a bunch of those. had something i think was called skyscraper kit for building buildings and of course the all metal erector set (u.s. version of mechano, marketed by a.c. gilbert) oh had lincon logs and leggos too. and brio or whatever they had been called back then, the wooden tracks and trains. never enough of any one of them to do as much creative as i had wanted to.
I was surprised to find out they still make this. There's actually a few YouTube channels showing what you can do with it (although I always thought it was pretty easy to figure out).
I think the patterns and results one can obtain have added to its longevity as they still look contemporary .
had tonka dump truck, dozer and end loader. built roads in the back yard with them too. at least a decade before what the model year of that camper looks like.
How about the old Jarts? What could possibly go wrong with throwing weighted sharpened steel projectiles at each other?
