Check out my bulge
Simple minds like simple things. I guess that's why I like basic geometric shapes like circles, triangles, and squares so much. What could be easier than assembling millions of different colored squares to create everything from works of art to the words that you're reading on your computer monitor right now? A different pixel here, a different pixel there . . . nothing much . . . child's play, really.
Another thing a child's mind delights in, for the purposes of this post, is optical illusions. I certainly remember that I liked them as a kid, and still do. Around the web you'll find many great optical illusions. One in particular that I like on that page is "A bulge". I like it because it contains nothing but squares lined up on a grid, yet manages to produce the effect of curved lines.
Needless to say, rectangular shapes are easy to produce with the box model of web layout. That's certainly the foundation of how I developed the basic Town Square spatial content system. So on a particular slow day I got around to reproducing the image using only div elements and a little CSS. Enjoy:
