I learned to use a slide ruler just for the fun of it, I even remember my Grand uncle showing me how an abacus worked before he passed on, A Nocturne? Why not? If I could get my hands on one. A seaworthy Re-blog sure.
That's pretty cool, an instrument of a bygone age... Just like the nocturnal. I learned about the abacus in school and how it worked, all long gone from the old memory banks now. It may be old technology but it doesn't make it any less cool!
