Sequin Flip puts interactive sequins on your desktop. Swipe up and down to flip them over and see the reverse color. The sequins realistically push on each other, just like the reversible sequins found on clothing, pillows, purses, etc.
The purple/green demo theme is free to use, and there are no ads, ever! The color settings are unlocked with a one-time in-app purchase.
The material type for each side can be metallic or plastic. For devices with a gyroscope, the sparkling reacts realistically as you move.
