A million-dollar pen vs. a pencil
You know this legend about how NASA spent millions to develop a pen that can write in zero gravity, and the russians have just used a pencil? Well, I was reminded about this by Dejan’s post in response to my post about the Random Gradient Wallpaper Generator.
I used an O(NxN) algorithm to generate a megapixel image that takes up about 5 MB on my desktop.
Dejan generated a 2x2 bitmap that takes up 70 bytes and let Windows stretch it with the exactly same effect. If you read my original post, go read this one, you’ll like it :)
