Who makes the audience-member- sawing-in-half illusion where you put a light up sign behind the box. After cutting, you lift the lower section up so the audience can see under that section to the back of the "sign". The sign is moved left to right a tad to aid the illusion.
Are there plans for it? I have seen it from the front and it looks good. I wonder how it appears to those not dead center.

Any input?
