Other, equally shameless thefts: the Harvard/MIT Algebraic Geometry Seminar, the Stanford Algebraic Geometry Seminar, the Brown University Geometry Seminar, the Geometry, Representation theory, and Moduli Seminar at Princeton, the Utah Number Theory Seminar, the Toronto Number Theory/Representation Theory Seminar, the Colloquium and the Arithmetic, Combinatorics, and Topology Seminars at the University of Michigan, the Algebraic Geometry Seminar at the University of British Columbia, the Seminar on Topics in Arithmetic Geometry, Etc. and the Baby Algebraic Geometry Seminar at MIT, the University of Connecticut Math Club, and the Utrecht Geometry and Topology Seminar. Also note the suspiciously colored background of the Aarhus Algebra Seminar and the Queen's Algebraic Geometry Seminar.
