When I was studying Computer Studies at school in the 1980s we had a trip to a multinationals office in Liverpool (built escalators, I think!) and were shown around their computer areas – rooms that held massive main-frames and made a racket. It was quite dull at the time, except for the fact that at the end we were shown a printout that used ASCII characters to generate pictures on a dot matrix printer. They were great – Mickey Mouse & Marilyn Monroe were two of them. I got to keep one, but of course soon got bored with it and chucked it away. What an idiot! They were fascinating - I always wondered how they created those images. I still haven’t found out, but I did find a site which does something similar. Upload a picture to Text-image and you can convert it to an ASCII picture, like this.
You can also convert it to something like this.
And this (the matrix effect).
Now that’s cool. You can also tweak the parameters to give things a bit of variety, as well.
I don’t know the maths behind it, but I intend to find out. It seems crazy that a collection of letters and characters can be used to create something so artistic, especially with the common or garden ASCII version. That’s all it is, in plain black and white… just letters and characters. I need to find out who came up with this idea.
