We've all had that moment where we're messing around with a game's files, and we accidentally turn the world into a strange, wrong-coloured nightmare, where all the trees are screaming and the sky is as black as a void, right? No? Ah, you're missing out.

Postposterous — whose video about Link's sunburn we covered last week — has been poking around in the game's memory like a curious brain surgeon lately, and he's made some... interesting discoveries.

"Once I find an area I know has some visual impact - I just change stuff randomly and 'see what happens'," he tells us. "Next thing I know, the trees went wonky and I knew I was onto something..."

These discoveries led to the video above, which includes weird purple fire, super-speed clouds, black water, and strangely iridescent lakes that Postposterous describes as "Listerine".

Oh, and by the way, these are the figures that Post has been messing around with:

Much like a brain surgeon poking around at areas of grey matter to see what they do, Postposterous has had to figure out what each number does, mostly by messing with it.

"I definitely discovered how to turn the burning embers on and off — the ones that happen when you're about to go into a blood moon reset. Definitely discovered wind speed. Definitely now have the ability to walk underwater (just got make the camera follow correctly). And a host of other things that affect the way the graphics draw."

Have these random, accidental discoveries led to any new mod ideas? "Absolutely," he says. "There's a whole underwater world that needs exploring! And if I can make the wind blow enemies away...imagine how hilarious that would be!

Stay tuned for Link's Underwater Adventures some time soon, then...
