An undergraduate student and I were discussing her senior project (an online exhibition of items at the Beinecke Library along with short critical essays on them) and noticed that we didn't have any horizontally-oriented themes for Yale Academic Commons sites. Not a problem any more, as we bought COLr from a freelance developer. I like this theme a lot and hope that some of you will find creative uses for it. Works well on multiple devices, but note that its strengths with media display could become a problem on low-bandwidth connections or could gobble up your data allocations on a cellular network.
Addendum 1: Almost in a procrustean manner, this theme resizes images on the fly to fit the available screen space. Lovely when you have big chunky images, not so great when you have something small. However, I corresponded with the developer and found out that you can prevent this from happening. It's a workaround for, at minimum, intermediate users. TO prevent resizing, add "noScale" as a style class to the desired image. You'll have to go into the HTML tab of the editor interface to make this change, and be sure that a) you add the class name to the existing style attribute of the image and b) you enter the class name exactly as written above, as it is case-sensitive.
