I thought I had already done this, but if so I can’t find it. Here are the full-resolution versions of all four Volvox meeting posters:

• First International Volvox Meeting (Volvox 2011, Tucson, Arizona) pdf jpg
• Second International Volvox Meeting (Volvox 2013, Fredericton, New Brunswick) pdf jpg
• Third International Volvox Meeting (Volvox 2015, Cambridge, U.K.) pdf jpg
• Fourth International Volvox Meeting (Volvox 2017, St. Louis, Missouri) pdf jpg (there wasn’t really a poster for this one; this is the cover of the abstract booklet)

Print them out 11 x 17 and wallpaper your door with them (just kidding, only a huge dork would do that).
