We're currently in the early stages of conference-tournament mode in Division I NCAA men's and women's basketball. Three conferences -- the Atlantic Sun, Big South, and Ohio Valley -- are holding their men's championship games today. Other leagues are currently in the middle of their tournaments, while the rest -- mainly the major conferences -- won't be starting theirs for a few days.
The host cities of many conference tournaments create special floors for the occasion. Below are a few of my favorites; these are from previous years, so you won't necessarily see the same designs this year. I encourage readers to submit, via the Comments system, links to photos of whatever conferences' tournament floors you can find!
Let's start out with the Big 12. Whichever year the following photo was taken, the conference came up with a design that showcased all 12 schools' logos, in what I would say is a crisp, elegant fashion that does not overwhelm (source).
Next, we have the Big 10. This screenshot from what is currently the front page of the conference website shows how a full set of school logos can be depicted in more of an "artsy" way, via a pinwheel motif at center-court.
Finally, for now, we have the Missouri Valley Conference. The MVC tournament earns my accolades not so much for visual aesthetics, but rather for its clever play on words in relation to its permanent St. Louis home: Arch Madness!!! (This is a screen capture from a freeze-frame of a YouTube video, so it's not all that clear. My apologies.)
Again, it would be great if our little online community of basketball-floor aficionados could document as many conference-tournament designs as possible. Thus, if you discover any good online photos, please post the links via the Comments.
