I've also been playing with design ideas. I thought of the idea of creating a design that was over 3000 pixels tall, that would incorporate each of the footprint displays on top of each other (carbon, garbage and water, top to bottom) but I don't quite like the direction it was going. I will however put it here to show process/see if someone else likes it:
It was about the time that I started working on the bottom of the design that I realized it really wasn't working how I had envisioned in my head, hence the funky coloring at the bit. Instead I decided to try and go with my garbage footprint design (with some modifications of course) and I'm working on the water footprint area.
You see, here is the original scale I was thinking on:
Each of those blue squares? Each one equals 2000 gallons of water, and there are 256 of them. Quite a lot of water huh?
THAT ISN'T EVEN THE ANNUAL WATER FOOTPRINT OF ONE PERSON! The average American water footprint per day is just over 2000 GALLONS. A DAY. I knew this was going to be quite a bit, BUT I WASN'T EXPECTING A NUMBER THIS STAGGERING FOR ONE PERSON!
So knowing that 356 objects per person isn't going to be something that a browser should be able to handle, I've decided to try looking into fluid dynamics and trying to do it that way. Sounds a lot harder right? Well I found this online: http://codepen.io/stuffit/details/hszvg
It's a free to use/modify/whatever code for fluid dynamics (it includes gravity, though the base example uses 0 as the gravity). I've already played with the code a bit, and it should be easy enough to incorporate into the scene, and if I add lines on the side to indicate the actual amount of water it is representing, it should be fine. (of course, still having scale indicators. Though it's going to be a tiny human if I go that route)
