Optical Illusion - Impossible Object With a Twist


[YouTube - Link]

If one looks closely at the construction of this figure, it quickly becomes apparent that something is just, well...wrong with it. 

This initially-baffling video exhibits how the human visual system can subconsciously interpret and thoroughly "see" a three-dimensional object even though it is impossible for such an object to exist.  Thankfully, the creator reveals how it was constructed.

Hey!

I bought my first typewriter, a Royal Royalite 64 at California Typewriter. They were really friendly there, luckily for me its a quick bus ride from the UC Berkeley campus.

SparkS in Ye Olden Dayes we did that all the time- We used the same ink for fountain pens and then we dipped the ribbon in it only with one edge so the ink was absorbed. The other trick was to re-moisten the ribbon so it gaver off ink for some longer. And so you could re-use the ribbon far longer than normal.We didn't think of that very much, that was just normal practise. We also learned from very young to readjust some of the levers and springs in the mechanical typewriters if somehow the tension on the keys became to soft or to hard. And once in a while you had to clean it from dust and too much ink because you got these blotty letters.

...But that was way before "DOS" or "Windows" - Géé I'm getting óld...!

:-D

I don't remember inking typewriter ribbons. I did ink printer ribbons though. I remember dipping a fountain pen in the ink bottle and pulling the lever down to fill up the rubber bladder with ink. One brand of ink even had bottles with a small reservoir of ink near the lid so you wouldn't need to dip the pen way down into bottles that were nearly empty.

Remember when a bottle of ink and ribbons were really inexpensive? Now you almost have to mortgage the house to afford printer ink.

Then came Teletype printers but that's a story all by itself. GGG

(we all know why printers are so cheap)
