I love it when people actually "THINK" and find a new way to employ a very old (and nearly forgotten about) principle! Quite clever!
Years ago when I was still working with Ken (Creative Illusions) we came up with a couple of different walking through Mirror bits, my favorite being one I've never produced commercially that incorporates some of Harrary's thinking; If you've ever seen Franz do the 2-D vanish then you have some idea as to how this piece looks except there are two parts in which the mage is "stuck" into the mirror. In phase one you have a total absorption into the mirror which can be spun about showing your entire body wedged into the glass front & back. In Phase Two the large spandex panels got back into play allowing for the 3-D reprise of your body but something seems to be "wrong".. the screens are removed revealing you partway stuck on either side of the mirror... then of course the penetration is completed.
It's not a piece for the faint of heart in that it is HUGE when assembled not to mention the rather hefty cost around it due to the technology that's being exploited, but dang if it's not cool

There are those times when I miss my big funky box tricks
