There was a library to use webcams for entropy called lavarnd up until about 8 years ago, as well. I am unsure if the api to the os changed or there's a functional difference between ccd and cmos or whatever.
I do a lot of entropy research, and was annoyed I had to roll my own implementation for a no-photon camera entropy source.
