How to model and stack firewood?

[joadhughes]

Like the title says, I need to model and stack firewood to go next to a fireplace. I will need 20-30 pieces of wood and I would prefer to not have to model each and every one. I tried just cutting a cylinder into a wedge, but the results are too flat and perfect. I want exactly this, but I would rather do it myself. http://www.turbosquid.com/3d-models/3d-wooden-logs-pile-wood-model/739632

 

Any ideas on how to do this without spending a whole day making individual logs?
