Samvera's annual Connect conference was held on-line because of the COVID-19 pandemic. A design had been created in anticipation of t-shirts at a face-to-face conference but it was used, instead, as the conference logo. 'Souvenirs' bearing the design were available via an on-line shop.
The team that founded the Hydra Project met several times in the fall of 2008 at the University of Virginia. At their meeting in December of that year the name 'Hydra' was coined. Later that same day, a hydra toy was spotted, and subsequently purchased, in a local shop - this became part of the first design used on the project's documents and presentations.
Two or so years into the Hydra project, around 2010, an on-line demonstrator was produced for the emerging software. The product was called Hydrangea. It proved difficult to keep up to date at a time of rapid development and was soon dropped - but it was in use long enough to get its own logo.
For Hydra Connect 2016, the local organizers took the project's basic logo and extended it. It was used on large display screens adjacent to the conference's main auditorium.
