Just go to any typical, normal transaction on blockexplorer. [Here's a link](http://blockexplorer.com/tx/bf89f7036bde78103b94cf1291c9389a5ed894045cebd5216f04f1a2aa5c5959) to one I picked at random. The input(s) are scripts where the public key and signature are provided to claim the outputs of previous transactions in the `ScriptSig` field. The output(s) are scripts where the public key has not yet been provided and contain only a hash of the public key in the `ScriptPubKey` field.
