I did a Google Hangout with my friend, Harrison, today, and he introduced me to a thing called Fritzing. Suppose you have a problem, where you can't take a picture of your breadboard, because there is a wire over one of the LEDs or something. Fritzing lets you make a cartoon-ish picture of your breadboard. You can put wires and LEDs, and almost anything you like on a virtual breadboard! Here is what it looks like, I'm sure you've seen something like this before: 


It's really handy, and I might use it for a tutorial on my Pumpkin Pi. I'm sure you can find this useful for anything from planning a game on your Raspberry Pi, to making tutorials. You can get it at http://www.fritzing.org/downloads
