Keith Cirkel has been building some interesting and educational web games lately:
- Hue Shift: “Two colours. One is fixed. The other is yours to bend. Drag to shift hue and lightness until they match.”
- What’s My ΔEOK JND?: “You see two colours. Click on the line between them. That’s it. It starts easy. It does not stay easy.”
- CSS or BS?: “We show you a CSS property name. You tell us if it’s real or if we made it up. That’s it.”
