Mizar Research Project has created two wacky projects for people "in long distance romantic relationships."

Telesquishy, made of colorless translucent rubber silicon, has to be hooked up with a USB cable to the computers of the lovers. When it's done, each other's squishing activities come over the Internet to light up the device. A blue glow means that the partnering squishy is not being squished. The red glow means that the partnering squishy is currently being squeezed. Varying degrees of squishing can produce an array of purple light in a darkened room.
The second work is Ambient Telepresence Windchimes . Once each of them is installed in the personal environments of both persons, they robotically induce their own chimes when the other senses presence.
