I've attached a sketch of an approach that I like. We actually chose the name "pando" to play off the networked tree system called the pando (http://en.wikipedia.org/wiki/Pando_(tree)), on the analogy that sharing information between faculty is like this majestic tree network that appears to be a bunch of independent trees but is actually a single gigantic tree network. The sketch we've done gets at that a bit with an abstract representation of 4 trees linked by a common, stylized root network. This is not to restrain creativity, but to give you an idea of the sort of modern, clean, and simple effect we'd like to obtain.
The example logos I have uploaded are good examples of a modern style that we like -- clean, geometric, largely abstract. The Beasely logo is the exception, but I really like the stylized leaves that convey an organic sense without being too realistic. Since the pando tree network is a living thing, and our workshops emphasize interaction and growth, we'd like to have some sense of organic design, rather than a completely abstract logo, but it should be pushed more to the stylized end of the continuum, rather than looking too naturalistic.
We'll be printing this logo on workbooks and other photocopied materials, so it should allow for a black-and-white representation without loss of impact. The uploaded example logos are good examples of this -- they can each be printed in B&W and still retain their character and clarity.
