  3. size(200, 200);
  4. background(100);

Works OK

This works nicely in WordPress 4.3.1 but I had to modify some of the characters in the processing code for javascript to run correctly, specifically:

The ampersand “&” changed to &

Less than “<” changed to <

Greater than “>” changed to >

This could be the result of TinyMCE messing things up during save, as is typical of WordPress.
