Redstone components

An And Gate, Or Gate, and Xor Gate. The And gate requires 2 inputs to become active and can be crafted with a redstone torch on the top left, top right, and bottom middle, a redstone dust between the 2 top redstone torches, and 3 stone from middle left to middle right. The Or Gate does either input to become active, but won't combine power strength if both inputs are active. Haven't figured a recipe for this one, but knowing you guys, you'll be able to come up with one. Finally, the Xor Gate, which can be active while ONLY ONE input is detected, and if both inputs are active, the Xor Gate turns off. You'll have to come up with a recipe because I still don't know how it would be crafted.
