Berkeley has a hippie mentality reputation even more than San Franciscans, but boy, those wonderful crunchy granola folks can have some great ideas for reuse!
I was visiting a friend, who is also my bookkeeper, and she had found an awesome reuse solution for glass blocks! Yes, that stuff that was used in the 80's, instead of windows and walls, which provide privacy and solar heat in homes and offices all over the Bay Area. It's so simple, I'm surprised that I haven't come across it on Pintrest yet. She had one 10" block halved to make a leak free planter for her succulents. Perfect for a desk in need of a little freshly made oxygen.
