Earrings - different shapes

People at work came out with an idea of creating earrings from prime blobs so then I started making different shapes for them. All of them are around 10mm in diameter, maybe little more. All you need to buy is the earring needle with the lock (hobby and DIY shops have those) and glue it on it.

Shapes:
Pentagon
Pentagram
Flower
Shirt button (that can be used as an actual shirt button)
Xmas tree
Pac-man and the Ghost (The Ghost should be scaled down to 80% to match the Pac-man size if you want to wear Pac-man in one ear and Ghost in the other)
