Laser Communicator to Photoresistor/Photocell

Using my homemade laser communicator so transmit sound to a photoresistor/photocell. This is instead of sending to a solar cell as I'd previously done.

The photoresistor can be bought here:

Note that it's been pointed out in the comments that much, much cheaper photoresistors that are suitable for hobbyists can be found on places like http://ebay.com. In my case I bought it from Adafruit as a fun additional item to play with while I was also buying other things (Arduino, servos, ...).

Some more explanatory calculations to do with voltage ranges can be found on my webpage here:
