Beaded curtains are seldom seen these days, but they used to be popular. Perhaps if some new technology was introduced, they could have a bit of a resurgence. This is provided for with the development of the Spooky Beaded Curtain.
it's spooky because it parts its beads automatically just before you walk through its portal. It can do this because each bead contains a set of tiny magnets, all connected to a processor via the hanging cords that descend from the top of the door frame.
On approaching the curtain a sensor evaluates the person's (or animal's) general body shape. It then delivers the necessary information required to activate the magnets contained in the hanging beads so that they attract/repel each other in the precise amounts necessary to full them apart, generating the exact gap shape required for the person to pass through.
After passing, the beads quickly relax back to their static hanging status.
