In Java, source files can contain unicode escapes[1] of the form '\uXXXX' which are expanded prior to tokenization. In effect this gives you several options for what characters can exist in a given "pixel". I think that this, combined with careful application of whitespace and comments, should easily provide enough flexibility to make arbitrary code look roughly like a desired bitmap.
