I entered in a rather nice design contest, based around a very neat technique for creating non-repeating website background patterns. The contest entry that gets the most re-tweets gets to win an iPad2. And I so much want one!
…and tweet, tweet, tweet. I was striving for something more minimalistic, more obvious and true to the principle, and more directly usable in various design contexts. Plus, I was naturally striving for something that looks good, which I hopefully have nailed in some way.
