Get your self prepared to celebrate tau day (http://tauday.com/) on June 28 with this tower of tow (or tau-er?). Why is tau better than pi? https://www.youtube.com/watch?v=83ofi_L6eAo https://www.youtube.com/watch?v=jG7vhMMXagQ Who will be the first to print this thing? The first one who prints this thing and shares a photo of it can name the next number that will be used to model a tower. Do you know any other interesting mathematical constant? Tweet it @RomanHegglin #towerofconstant or leave a comment. This is a part of a series of towers/penholders made out of digits.
