Touch light sensors

Hi there,

I am trying to put together a fun project for children and want to give

them an introduction to building their own kits.

The current project that we planned for is to build a tap light that

eventually we can program to form patterns.

Our requirements for a sensor are as such:

-able to display lights (at least 4 colours)

-battery life of at least 4 hours

-display screen to show simple numbers/ shapes

-ability to communicate with other tap lights via a software or program

-touch/tap sensor to activate/deactivate

Do let me know if I can provide any more clarification.
