Learnin' Electrical Engineering

Are there any resources available over the web where I can learn circuit design and electronics? I used to have a kit from Radio Shack that came with a book of experiments, a breadboard, a bunch of wires and a shitload of transistors, resistors, capacitors, switches and a couple ICs. Are there any flash apps or commercial packages available that can emulate such things?

Dare I say, spice is pretty useful once you figure it out.
