I didn't realize until a day later, that my "waiting" tile, had eggs in it! So even though it was created before the challenge post, and not with the challenge consciously in my mind, I figured maybe the challenge vibes didn't need the computer at all. (Twilight Zone music here, maybe?)
The second one was doubly inspired: first by the challenge, and then by Margaret Bremner's new tangle, Diamond Panes. Once I had made an egg-shaped string, the tile said to me, "Please try Margaret Bremner's new tangle on me!" I loved how she used it in her sample: how the shape sort of floats above the new pattern. I could see why my little egg was so insistent.
I also felt compelled to scan the challenge tile before shading and after, since I thought it would be a good example of how simple shading can make a difference. Even just a bit of shading around the outside of an object can make lots of dimension! One of the things I love about the Zentangle® art form is that simplicity is what makes it accessible to everyone. You can go simple or complex, and it's all fun!
