Holographic Displays/Tactile Interface

Oh, the wonders of technology. For those of you looking to reenact the Princess Leia hologram messages from Star Wars there's now a spiffy heliodisplay that lets you interact with your monitor in a three dimensional fashion.  Another kicking UI that'll let you play with your hands is this tactile display (kind of like Minority Report).

If either of these technologies ever becomes widespread the smutty possibilities are endless.
