Just an update that the torus balloons are being posted out in waves. But splitting them into batches it makes the logistics far more manageable, so sorry if you are still waiting. I'm trying to go roughly by duration-of-support order (it was that or totally random). The next release should start hitting mail boxes in just over a week.
I am still missing postal addresses from a bunch of people. In theory you can go into your Patreon 'manage membership' settings (or profile settings / shipping address) and you should be able to add your address to your Stand-up Maths pledge. But if you cannot or don't want to do that, I have set up a google form for you to give me your address.

Any postal address you have in Patreon will take precedence over my form, but if I do not have an official contact address for you from Patreon, I will use what you put in this form.
And I will not leave anyone behind! As we speak my self-made python mail-merge code is running and emailing everyone I am missing an address for. I will email again at the end of September (or so) if there are still any supporters I am missing an address for.
Finally: Yes, the first batch of cards had a typo and said "ballon" instead of "balloon". Don't worry, the person responsible was fired. And then immediately rehired. Because it was me. I have ordered a fixed version of the card, but I think if anything, it makes the error cards even more special because of their limited edition nature.
UPDATE: A few people have asked if their balloon can be donated to someone else. Which is a great suggestion! I'll ask for nominated schools on twitter. But if you wish to direct your balloon to a specific school just use this form and enter your patreon email so I can match it up. https://forms.gle/YirXBgcprjrBrG926
