Numberphile

<a href="https://www.youtube.com/user/numberphile" rel="nofollow">Numberphile</a> is all about numbers and mathematics. Here on Patreon we're asking for help making our films that little bit better - and offering some treats in return. We'll have plenty of bonus features for patrons, including appearing on our Wall of Fame at <a href="https://www.numberphile.com/patrons/">https://www.numberphile.com/patrons/</a> There's also a chance to have your name appear in the videos and video descriptions. On our feed we post occasional secret videos and photos shared only with patrons. You may receive occasional extra items (make sure to include an address) and of course there's a chance to get your hands on our (in)famous brown papers! Funds raised here on Patreon will be used&nbsp;to create more animations, travel to meet mathematicians and&nbsp;pursue some of our more ambitious ideas. In true Numberphile style, we've had fun setting the reward levels. Regardless of whether you can contribute, our channel is free for all. And the best thing you can do for Numberphile is just keep watching (plus maybe tell your friends about us). Numberphile's main sponsor remains the&nbsp;<a href="http://www.msri.org/web/msri" rel="nofollow">Mathematical Sciences Research Institute</a>, where we regularly visit and film the world's top mathematicians. The project would not exist without them.

Perfect Supporter 
Put this here because we wanted a "perfect number pledge" and 8128 would have been truly ridiculous! 
- Occasional special bonuses associated with the project. 
- Join a hang-out with Brady to discuss what he's working on (and tell him what he SHOULD be working on). 
All previous rewards also apply of course (and, wow, you must really love numbers!)
