To limit the spread of infection and at the advisement of the State of Montana (what's up Governor Bullock!) we have temporarily closed our warehouse. Items that were not shipped before we closed on Friday March 27th cannot currently be shipped because we only have one person in our warehouse keeping things secure and ensuring that the Hanklerfish don't get up to anything funny. This also means that we are unable to process any replacements or returns at this time. Seriously, though, this sucks but we are doing our part. - The DFTBA Team

Specifically, it is about animating math, not just in the sense of explaining otherwise complex topics using moving visuals and anthropomorphic pi creatures, but also in the sense of giving life to a subjects whose beauty often goes underappreciated.
