eTop Euler’s Constant Inspired Desk Toy

Here is another cool desk desk toy from Sirius Enigmas. It is a copper oblate ellipsoid inspired by Euler’s constant e. It can be spun vertically and horizontally with a magnetic stirrer. It measures 2 inches in diameter and is 2/e” thick at its widest point.

You can experiment with all kinds of lights while your eTop is spinning for more trippy experience.
