Pi Illusion Cup

Is this cup taller than it is around? How do you think the height of the cup compares to its circumference? If you ask your friends and don't let them measure, most of them will say that the cup is much taller than its circumference. However, this cup is actually SHORTER, and we can prove it with the help of the number pi. To see the proof and learn how this model was made using the new features in OpenSCAD 2015.03, go to Hacktastic: http://mathgrrl.com/hacktastic/2015/03/pi-day-openscad-celebration/ ===== #####Twitter: [twitter.com/mathgrrl](https://twitter.com/mathgrrl) #####Hacktastic blog: [www.mathgrrl.com/hacktastic](http://www.mathgrrl.com/hacktastic) #####Shapeways geekhaus store: [www.shapeways.com/shops/mathgrrl](https://www.shapeways.com/shops/mathgrrl) *This design and all associated pictures and files are licensed under the [Creative Commons Attribution Non-Commercial Share Alike](https://creativecommons.org/licenses/by-nc-sa/2.5/) license.
