"Big Scary Laser" logo copyright?

Does anyone know the source of this image:

Like, who originally created it?

I see they used it in the TED demo of the mosquito-zapper laser;

How to shoot down mosquito using laser gadget. - YouTube

I guess no permission was required to use this image (no copyright)?

I have seen it in the serial "the big bang theory". But I am not shure if it is from there.
