iBar is a bar surface that can display images and interact with patrons by detecting objects touching the surface and interactively changing its display.

Especially cool is their demo display, which draws glowing lines connecting the objects touching the bar. I love how the display flirtatiously implies you are somehow connected to other people sitting at the bar. It reminds you that even if you feel isolated or distant from strangers, you have a great deal in common simply by proximity. There should be more technology like this.
