I fiddled with this one a couple times since I first posted it.
The fonts are Yikes and Century Gothic. Both fonts are free for private or commercial use, which is important since I want to sell this eventually and it’s always nice if I don’t have to worry about licenses. The larger one is an example of what you can do with text along a line. And then I fiddled with layer effects to get this look. I didn’t actually warp the text. I just upped the font size a bit on each letter as I went around the spiral.
