Saving you a click, it's just a bunch of pictures of hot air balloons with 'Make Smalltalk Great Again' written on them (often barely readable due to color and font choices)
I think those pictures are rather cool. Some of them blow me away!
Yes, it's just "a bunch of pictures." That's his gift to us.
The backstory about how hot-air balloons came to be Smalltalk's logo is interesting.
