If nothing obvious jumps out in connection with current hobbies/interests, time to consider a new one. Is he arty? Likely to study art/design/media - perhaps a decent DSLR camera starter kit? Also works for those interested in nature/wildlife/ecology.
The thing about starting someone off with photography (or similar) is that the years ahead are covered by gifts of accessories - lenses, cases, filters, cards, batteries, remote shutters, tripods, experience days.
You can get Canon EOS DSLRs quite reasonably nowadays. If you start with a 1200D, you also give yourself the opportunity of trading up to a 700D etc in future (the lower the number in the series, the better the camera).
