For those interested, here's what I was able to read from the twitter avatar:

    Pro Tip: You can add more
    than 140 characters into
    your twitter avatar. For
    example, here are 156 of
     them. Just make sure to
    include all links in the
    main text ;-) Also, hand
    out magnifying glasses!

Thanks! I was trying to decipher it on iMac with a 5k display (? 5120x2880) and an attached LED Cinema Display (2560x1440). MacOS does a good job dealing with the DPI so that they appear the same size (but one is clearer than the other). Using a magnifying glass, I could almost make out the text on the lower DPI screen, though blue was almost invisible, and I could not seen anything other than a colored bar on the high DPI screen :)

I tried using my native resolution on my MBP Retina and then taking a photo and zooming in. Nope. I could only decipher the ;-)

From what I can tell, it says 198 characters, not 156. ;-) You can count the characters yourself, if you'd like.
