I was reading an article in Next Step Magazine that talked about this. They suggested several "innovative colleges" which were as follows:

• Bard College (www.bard.edu) in Annandale-on-Hudson, N.Y.  At Bard, student written "zines" - which are homemade, low-budget magazines are popular and they write about anything from music to politics.  Bard College has the largest "zine library" on the east coast.

• Bennington College (www.bennington.edu) in Benningon, VT.  Students design their own personal interdisciplinary courses and receive detailed written evaluations, not grades.  The interdisciplinary format allows students to learn about a subject in depth and connect themes or ideas.

• Earlham College (www.earlham.edu) in Richmond, Ind.  Sixty-four percent of the students at Earlham study abroad through opportunities like peace studies programs in Northern Ireland and the Middle East.  Many of the students are also active volunteers collectively contributing 30.000 hours to volunteerism.  The objective of this Quaker founded school is to bridge the gap between theory and practice. 

• Eugene Lang College (www.lang.newschool.edu) in New York, NY.  Eugene Lang is part of the New Scool for Social Research and offers opportunities to intern at the U.N. Relief Work Agency, teaching kids to read in Harlem or learn directly from curators at the Museum of Modern Art.

• Evergreen State Collge (www.evergreen.edu)  in Olympia, Washington. They enroll in interdisciplinary programs, not individual courses. Each program explores a theme or question such as "Writing for Change" or "Music, Math and Motion."

• Hampshire College (www.hampshire.edu) in Amherst, Mass.  Here the longest running student group is Mixed Nuts, a food co-op that provides organic food to students and community members.

• Marlboro College (www.marlboro.edu) in Marlboro, VT.  This college is very small with an enrollment of 330 students which allows for close interactin with faculty, including advanced one-on-one instruction called tutorials.

• New College of Florida (www.ncf.edu) in Sarasota, FL.  This school has approximately 800 students and students call their factulty by their first name and meet with them at the cafes fto discuss philosophy.

• Reed College (www.reed.edu) in Portland, OR.  This is somewhat of a quirky, intellectual college that offers theme dorms, including one about ancient civilazations and an organic-friendly co-op.

• St. John's College (www.stjohnscollege.edu) in Annapolis, MD.  This is a small but rigorous college with campuses in Maryland and New Mexico.  There are no textbooks or lectures.  Instead, students read great workds of literature, study mathematics and learn to wrtie classical music.  At the end of each semester there are no grades, but the students must meet with the instructors for an open discussion evaluation.

These are just ten "innovative" style colleges that you may want to consider if you are looking for something non-traditional.  These colleges are for the free spirited, non-conforming type of student.  My suggestion is to do your research carefully and meet and talk to students and faculty at these campuses before making your final decision.    
 
Best of luck!
