Lio
Thanks to Danko for linking to this wonderful comic strip: Lio. I'm going to have to second his recommendation.
Lio is a comic strip without dialogue. No word bubbles or anything, just a few sound effects. Each comic is carried off by a simple series of pictures, and it works wonderfully. It didn't even occur to me to expect dialogue for the first few. I've heard Lio compared to Calvin and Hobbes and I can see a connection, but I wouldn't have said that myself. Both strips are too unique for that sort of comparison. I highly recommend Lio.
Here are a few of my favorites:
