For my Plush Night Light I am making one of the four elements.
I have bought eight ambient LED that change brightness constantly. You know, the kind of LEDs in fake candles.
I will incorporate these into my Plush element and I am not planning on using Arduino.
I have sketched three:
In this one the Fire Plush should light up like the fire in a Candle.
This should have the effect of glimting water in the sun.
The Moss Plush represents Earth and should have the effect glimting moist moss in the sun.
