Ask HN: Morse code easter eggs

I wanted to insert a visible but really discreet morse code easter egg on my company website and I'm curious if anyone knows other websites that have done something similar. I will not put the URL here because I don't want it to look like I'm promoting my company or anything, but I would really want to see how/if others have done this. I've added it as an "active" selector for the "what we do" menu item. The morse code basically explains in two words what we do :)
