Radical Pi is the undergraduate math club of The Ohio State University. Each meeting consists of a presentation by a faculty member or (sometimes) a student, which is advertised beforehand via e-mail and a poster. The speaker provides the title, abstract, and occasionally some images, while one or more Radical Pi members create the poster using these ingredients.
The list of Radical Pi meetings can be found here, with links to speakers, posters, and other details.
I was the primary creator of the posters below (2012–2015), with assistance and feedback from Andrew Krieger (2012–2014), Benjamin O'Connor (2012–2014), and Duncan Clark (2014–2015). These posters were advertised through e-mail and physical placement in and near the OSU Math Tower and Math Building.

(The equations for the graphs are Re(𝜁(1/2 + ix) and Im(𝜁(1/2 + ix).)This poster was used to advertise Radical Pi independently of any specific meeting.
The Fourier series for a square wave graphed on the poster is a homage to the box art of the Casio fx-9750G graphing calculator.
