I have a lava rock fireplace. Let's make it erupt!

It's your basic lava rock fireplace. There's electricity in the back.
I know folks who are into LEDs, Arduino, and Maker-type frivolity. The effect I want is lava pulsing between the crevices, as if it were about to blow. Think it can be done? Please tell me more.
