I took a picture of the inside of a ribbed water tumbler. Nice spiral, looks like the Time Tunnel (remember that awful show from the 70s?). Then, superimposed the outline of a dump truck wheel. Wheels within wheels.
This is one of the things I love most about having a blog: it’s a bully pulpit. If it totally expressed my vision, I can post as many variations as I want. If nobody besides me likes it or thinks it’s good, that’s ok too, because it’s not about impressing someone. And I really, really like creating pictures like the one above. Sometimes when I’m editing, I try a setting and instantly know that it’s just right. When I saw this, I pumped my fist and said “yesssss” and immediately saved it and — here’s the key — STOPPED EDITING. Didn’t “just try one more thing”. If it’s right you know it.
