In 2009, I took these pictures of a mural in Cologne, probably made by children, showing some aliens. One of them remained unfinished (or is it just materializing from hyperspace :)? That was arround the time when I wrote my first Tsish-articles.
I have no idea how Tsish looks. Maybe like this? If you have any ideas how Tsish might look or you see some fitting pictures on some wall, please post them and put a comment with a link here. Since Tsish is a fictional character, he/she might look different at different times (depending on the settings of his/her asifomat).
I like these aliens because they look friendly and happy. And the pink space ships are so cool :-)!
Update from May 5th, 2013: I just passed there again today, this is how they look now. Note that the third alien has been given a face and some alien inscription on his ship (unfortunately, we don’t have a translator :-)).
