...and the Two Hard Problems
(no.lastname.nz)
Had this idea off and on again for a while now, but this time I happened to be in front of a computer when inspiration struck.
Made with GIMP 3.0.4. Yes, I used the awkward {selection + normal fill + smaller selection + erase fill} method to draw the circle. There was also a bright spot in the image under the text that required a drop shadow.
Have you run the numbers? There's a serious competition there.
