I especially like the "Tetrahedraharp 2000 - This 3 sided pyramid has 36 strings and fits over the head to produce a mind-altering "Lost Chord" effect that is most ecstatic and healing. (I'm not selling these yet, but will be doing recordings.)" I wonder if the lost chord effect could be lost and found again with the help of earphones and a walkman? I also enjoy the concept that you can practice and go skiing at the same time. Someone should construct a sitar and surbrahar "in one fell slope" before he does.
