Morse code in this doodle? think Interstellar (movie)
I think the OP is referring to the flickering of the candle in the animation. That doesn't look like Morse code, unless the message is something like EEEEEEEEETEEEEIEEEEETEETEEEEEEAEEEEEE. It's possible a message is encoded in there somehow, but if so the encoding isn't just Morse code.
Sadly I did not see any Morse code but that is a great idea! Comment (since I'm not allowed to comment I will add it here): I know it's the candle, I watched it in slow motion. It does not have Morse code because it is almost perfectly periodic and every now and then it has a slight glitch probably when the CPU or browser is busy with something else for a split second and a little late when updating the graphic.
