My daughter attends RIT. She is a graphic design major, interested in either ui or motion graphics. They have excellent resources, and are especially known for their photography, design and ceramics. RIT is foremost a hands-on, career oriented university, as is their art program.
Regarding bridging disciplines: read about their brand new MAGIC Center http://magic.rit.edu/studios/facility/ which is committed to bridging the gap between art and technology.
Their graduates of their New Media Design B.F.A. program https://www.rit.edu/programs/new-media-design-bfa are especially employable (if that is part of your matrix) with top students exiting the program making $120,000. With a B.F.A. RIT also has a co-op system, and the New Media Design majors have worked at such places as Google. The College of Imaging Arts and Sciences (CIAS) is RIT’s Art College as an umbrella over the various art schools (school of design, school of film/animation, etc.)
My daughter also liked Ringling and Laguna, but neither gave her much financial aid. (RIT gave a decent aid package - it is costing us less to send our daughter there than it would have to our state art college - the facilities are much nicer.) The best thing my daughter did to get ready for portfolio reviews was to spend a month at the Ringling Pre-College program, where it was demanding, and expectations were high. I also recommend looking at VCUarts - we were impressed with the facilities and the art that we saw touring. It is better for fine art rather than digital art. Ultimately, my daughter decided on RIT because 1) the work coming out of RIT was of high quality; 2) they gave a decent aid package; 3) the facilities were/are excellent; 4) she liked the “career readiness” aspect of their design program.
In the meantime, if your son is interested in art and media, he should try his hand at MAYA (free for students 3D animation software - they offer lots of free online tutorials). Also Illustrator, and if possible an object oriented programming language. Excellent designers who can do 3D, 2D and also code are worth their weight in gold.
