Okay, so I'm curious about something, and this is entirely for future reference, so don't get too excited just yet. I also apologize if I'm not articulating myself very well, since I know very little about how this works.
Now, I happened upon this site a while ago now, and it remains to be something that absolutely stuns and baffles me every time I look at it.
The artist says that he and another programmer used HTML5 to make these images, which are like traditional canvas cycling pixelled images seen in older games.
This is the site in question: http://www.effectgames.com/demos/canvascycle/
I highly recommend going through it to see what I'm trying to describe here. Basically, though, they are images (with pleasant accompanying sounds, I might add) that have certain pixels cycling in color to create animations (most of which you see is precipitation and moving water).
Now, out of curiosity... is anybody on here able to do that? I've mentioned before that a friend of mine and myself want to open a site that is slowly turning into something exclusively pixel based and we'd love to have our maps be like this. However, we'd love to have different weather patterns and light cycles happening on them as well (not that these would cycle but I think you get what I mean), and I'd love to know how it works or if anybody can help me do this so that I don't have to make the animations myself, as that is incredibly complicated. It just seems incredibly fascinating.
