Is there any open-source white-box implementation of AES or DES? I googled it, but got no result.  There is a binary executable of a white-box implementation of DES (scroll down), but no source code is provided.

The same page also links various papers about white-box cryptography, but these don't contain the implementation.

I want to study such an implementation to learn about the techniques used there.
I add my whitebox AES implementation on GitHub in:

C++
Java

C++ version implements both Chow's (mixing bijections, input/output encodings, external encodings) and Karroumi's (dual AES in each column) whitebox AES scheme plus Billet's key recovery attack on both schemes.
Java implements Chow's scheme only.
PS: Due to low reputation I post links to schemes to the comment below.
