Designer Avery Holleman has developed the concept of a Napkin PC, a device that uses e-paper and radio frequency (RF) technology to enable creative groups to collaborate more effectively.

The technology includes a “napkin” holder filled with rewritable e-paper napkins, as well as a place for colored pens. When someone gets an inspiration, they simply grab a napkin and start doodling with one of the pens. The pen uses short-range RF technology to send data to the napkin interface. The pen and napkin can also communicate to a base station PC in the napkin holder using long-range RF.
