Even when I was like six or seven, one of my favorite things to do on the computer was get on Paint, zoom in to 800%, put the grid on, and start drawing things pixel-by-pixel, although I did not know that they were called "pixels" then.  I didn't draw much on the computer for a while, but lately, this hobby has resurfaced, and I've tried drawing more advanced things than I used to, such as an isometric room, some close-up playing cards, and a nicely-detailed(for a beginner, anyway) Mountain Dew can.  That is my life, pixel-wise.  No, wait...that is my life, period. :)
