As a software engineer, the first thing that jumps out about Vi is her name. Vi(m) is a famous text editor used by a huge number of IT folk, and if I had to guess, Vi is a tribute to Vi the editor, which is awesome. (see vim.org)
Vim (the most commonly used version of Vi) is charity-ware, the author asks programmers who use vim to donate to their orphanage at: http://www.iccf.nl/news.html
Given I can guarantee that vim has been used at Riot to bring us this amazing game, it would be immensely impressive of Riot if they donated a small % of Vi sales to the official Vi charity , and made a bunch of orphans better off in the process.
Go on Riot, show us what you're made of
