Computer punch card window shades

Jeff writes – “In some sense I’m using computer technology to both block out the sun and help me sleep in. With a box of old computer punch-cards, a used vertical blinds assembly, and some needle and thread I fashioned a device to help me in my ongoing battle against my bodies desire to wake-up.

We have where I work boxes upon boxes of these prehistoric paper punch-cards. I’m always looking for novel ideas to put them to good use again. Besides being good for blocking out the sun they also make good book marks and table leg stabilizer’s… I think the cards I used were ‘saved’ Fortran programs.” [via] – Link.
