I feel it is definitely possible to perform magic/mentalism for someone who is blind, and to create a magical experience for them.
I feel it is possible to make anyone feel this... no matter the disability.
Don't see there disability as a problem, more as a challenge for yourself to be able to give them that feeling of magic in spite of there problems.
I say challenge... but I mean as in don't let it stop you from bringing them that same feeling of wonder as you bring to others.
Performing for a blind person would obviously mean that visual effects will fly over there head... but they still have there sense of touch and smell, aswell as hearing.
Also there mind is still there own...
Adapt, be creative...
Some form of mentalism would be ideal, such as psychological forces of varying types. Though they can't see, how about you take advantage of there sense of touch, you could make effects specifically for someone who is blind, with bumps and grooves on cards that they can feel so they know whats on it etc... or a book test with one of there special bumpy book things.
Maybe do a reading of some type, such as a palm reading or gem stone reading. How about instead of reading there mind etc, you lead them on a journey... one where they get to experience certain feelings such as happiness etc, you could then anchor there feelings etc and use various methods of hypnosis type things to enchance there experience.
They may not become astonished etc, but they'll experience something, and you'll be experiencing it along with them... it'll be something they'll remember for sure.
You could allow them to feel like they have a special sense etc, like threm become the mindreader... things like them revealing something that another spec is thinking or doing, or you yourself... as long as it's fun and entertaining for them at that moment in time... well that's what matters.
Anyway ive blabbed on long enough lol.
