The html for the colloquium page is one of a multitude of pages shamelessly stolen from the 2000 Michigan Algebraic Geometry Seminar page, which was designed by Pasha Belorousski and subsequently stolen by every algebraic geometry web page in the country. Here are a few others:

• Columbia Algebraic Geometry Seminar
• Brown University Geometry Seminars
• Harvard/MIT Algebraic Geometry Seminar
• MIT seminar on topics in arithmetic geometry
• Stanford Algebraic Geometry Seminar
• Utah Number Theory Seminar
• Toronto Number Theory/Representation Theory Seminar
• Michigan Colloquium
• Michigan Arithmetic Seminiar,
• Michigan Combinatorics
• Michigan Topology
• Michigan Geometry
• Michigan Student geometry and topology
• Michigan Teaching math seminar
• UBC Colloquium
• UBC Algebraic Geometry Seminar
• University of Connecticut Math Club
• Utrecht Geometry and Topology Seminar.
• Queen's Albegraic Geometry Seminar.
• Also note the suspiciously colored background of the Aarhus Algebra Seminar.
