Some works by Rex Ray do have round, dot elements in them and that qualifies him to be seen here, but the real reason I'm posting about him is the inspiration I felt after reading this article about him in the 8/08 ArtWorks Magazine.
Sometimes we feel like we're having a bit of a rough day, which affects our art-making. Hearing him tell of the experiences he's faced made me realize how cushy and spoiled we can get; letting the smallest things throw us off track. As with any good artist, it's hard to pick just 1 or 2 images to represent their work and whet your appetite to see more.
So you'll want to visit his Website and there's quite a fascinating bounty of pics and info at Squidoo.
There's a YouTube interview Here, and you can watch him working on one of his larger pieces Here.
