Supersize neon sign

[stuee]

Hi.
I would like to make one of these
**broken link removed**

but about 1m x 2m big.
Am i under the impression that they use led lights transmitting through the glass?
Could someone point me in the right direction how to do this and what leds / pens.

thanks

This is a sheet of glass on a black background with LEDs on the edge of the glass. The light is transmitted through the glass and gives a kind of back lighting to anything drawn on it.

Any white LED will be ok, not sure what brightness you would need but you can always make bright one dimmer, you cant make dim ones brighter!
any whiteboard / non-permanent marker pen will work.
