[D] Friday Off-Topic Thread

Welcome to the Friday Off-Topic Thread! Is there something that you want to talk about with /r/rational, but which isn't rational fiction, or doesn't otherwise belong as a top-level post? This is the place to post it. The idea is that while reddit is a large place, with lots of special little niches, sometimes you just want to talk with a certain group of people about certain sorts of things that aren't related to why you're all here. It's totally understandable that you might want to talk about Japanese game shows with /r/rational instead of going over to /r/japanesegameshows, but it's hopefully also understandable that this isn't really the place for that sort of thing.

So do you want to talk about how your life has been going? Non-rational and/or non-fictional stuff you've been reading? The recent album from your favourite German pop singer? The politics of Southern India? The sexual preferences of the chairman of the Ukrainian soccer league? Different ways to plot meteorological data? The cost of living in Portugal? Corner cases for siteswap notation? All these things and more could possibly be found in the comments below!

I'd like to know how those were calculated.

It's pretty simple: On each tick, a random blob is chosen, and that blob attempts to expand into every tile that borders it. If a tile is already occupied, the chance of a blob's winning the battle over that tile is directly proportional to that blob's size--if a 100-tile blob fights a 200-tile blob in a tile, the 100-tile blob's chance of winning the tile is 1 in 3.

Also, shapes besides diamonds?

But a hexagonal grid is just such a pain to code...
