EDIT2: Changed the license to cc-by because people are selling it without any modification and without giving credit. However, I DON'T REQUIRE ATTRIBUTION IF YOU USE THIS AS PART OF YOUR WORK, MODIFIY IT. I wish there were other license types. I wish my work could help as many people as possible, like Blender does, but selling it as is not nice.
EDIT: File updated to use the new Cycles SSS, hair and packing habilities.
This are the strawberries I used in this video
The last 2 layers are what I used to (almost) procedurally generate the strawberry. One is the strawberry itself with hair and the other is a copy meant to hold the seeds as particles. You can recreate it from the last upper layer.
They are in groups, which I use as proxy in the main render layer (the first one).
The second layer is just lights. They have a .exr texture from http://www.hdrlabs.com/sibl/archive.html and the world has the wildly famous kitchen.hdr
The texture of the strawberry is all procedural, using a noise texture to deform the UV itself. A very cool cycles option.
Finally, there is the compositor. Nothing too fancy here.
