(the ones with the motors).. and times it by 100. That's Capsella. You could build machines, and tiny robots. Structures, and just funky abstract art with these clear plastic bubbles. Some were battery-operated, some had gears inside, others were just hollow. They were beautiful and neet, unfortunately ghastly expensive. Usually the only one who had Capsella was the rich kid who got it for christmas, and never played with it. I bought myself a huge set a few years ago to make up for not having my own when I was younger.
Capsella always reminded me of the buildings the doozers
made on Fraggle Rock
