Spreadsheet Art

I bought the most recent issue of "Wired" magazine and read a short little blurb about a lady who makes art with spreadsheets. By making all the cells squares and changing the background colors, fabulous mosaics can take shape. I was surprisingly fascinated by this, maybe just because it makes so much sense, so I started fiddling. I'm not to the point of creation, only replication, but I'm still really impressed with the results. My creations have all been Mario, because it's 8-bit and blocky, therefore easy to create. Wanna see? Here are the pictures of my works of art.
