Light Touch devices allow you to exchange coloured lights with friends and family across the internet. When you choose and send a colour, it pulses on the partner device then fades away slowly, so you can use them in realtime or leave traces for them to find later.
Each Light Touch has two LED lights: a “send” light that you control from your device, and a “receive” light that your partner controls, as well as a touch sensor or button for selecting and sending colours. To select a colour, press down on the sensor, wait while the send light cycles through colours, and release when you find a colour you like. Then simply tap on the button to send your choice. The receive light on the partner device will light up instantly as a visible indication of your attention. That’s all there is to it!
