MIT hackers have long considered “Tetris on the Green Building” to be the Holy Grail of hacks, as the side of the building is a wonderful grid for the game.
The game started off scrolling the words “TETRIS” and then would start into the first level. As the player progressed, the second level would start with more pale colors, making it harder to identify the type of block. The third level involved the colors shifting on-screen. Upon losing the game, all of the blocks would fall to the bottom of the building.
How would you arrange 100 dots so that no two were too close, but no dot was too far from the centre. The answer would be useful in nature, where the dots might correspond to growing structures which can’t be overcrowded. One solution that evolution has found is the Fibonacci spiral, in e.g. a sunflower head. This animation shows the output of a program which tries to find a good solution. At the start the dots are placed randomly, then each dot is moved in turn to a better position in the image. [code]
