This week, we had a young visitor hanging out around OtherFab. My son is 8 and was on spring break. He loves it here and begged me to come to work. I said he could come for half of the time, not really being sure how to juggle the workday with watching a kid. Fortunately, he is into building things (so are we!), so I figured that I could use him as a beta tester for some of our software and hardware tools.
