It's really good - I'll be using that for stuff at home. Can't believe this kind of stuff is a) free and b) browser based. I'd bet that somebody is working on export to eagle schematic format too - simulation to schematic to board layout for £0, brill.

Only minor issue if this were used in school - the resistor symbol is incorrect if it was to be used in an electronics lesson.

It is a while since I did my electronics. I thought that was the symbol for a resistor. What should it look like?

That symbol was retired before I went to secondary school in 1996 (for electronics, but not in physics). The new symbol is simply a box with a line going into each end.

Americans still use the squiggle, but that is used in UK electronics, as it also allows for simple alteration for variable resistors and thermisters etc... without them looking messy (as they do with the squiggle)

Nifty. Found this elsewhere actually and searched here before posting :)

Does anyone know of something similar that is fully virtual? I.e. you can introduce power to a circuit and see certain effects (voltmeter, motor, LED, buzzer etc) and faulting effects? (too much current/blown components)
