Since my son has really gotten into his yo-yo I've decided to bring my yo-yo's from work home. He got his from Grandma/Grandpa while at the Boston Museum of Science about a year ago, he just recently rediscovered it.
All three kids were quite shocked at my 'collection' of yoyos. As a Software Developer, I used to use a yo-yo in meetings and in thought, or while in a "wait state" (waiting for something to build, reboot, run, etc). I haven't actually used them in a long, long while so I brought them home tonight. I realized that I *might* have to get a few more to round out the collection ;-)
