15% of 3M

Today's (local) 15% feature comes from a decade (!) old article on Wired.com, basically stating that for decades, the engineers at 3M have spent 15% of their work hours on their own projects. This is good for 3M, because their projects have become 3M's products.

I don't know if I'm more blown away by the article being as interesting as it is, or that 10 years ago it was 1998.
