Circuit designer software

Hi all, Anyone knows what program that is used to design the circuit like this one .

I am looking the software application that can use to design like that one. I am really interested on those designed.

and also produce a schematic like below :

Thanks before.

Is this what you were thinking of:

Just a matter or terms, that isn't a simulator. I only say that because if you look for or ask about "circuit simulation" software, you will get something very different.

Sorry James, I didn't now how i say for that kind of software...however, thanks for u'r suggestion.

Is this what you were thinking of:

Is fritzing could produce like those one?

it produces something similar, I have a feeling those specific ones were done in an art package
