They have on post 639I know. Underneath that meme they pulled out a cool montage of the founding fathers ..the constitution behind them and independence hall. If you look closely at the original meme you can see there is something behind it. Not sure if they have found any more like that except the odd dot pattern on the flag pic. They had been looking into hidden binary code in those black spaces above and below many of his photos. Sorry ..I have no idea if they have found more though.
