[feedback] cool guest (warning: UI-obsessed)

[cosenal]

Perfect guest.

The only warning: if you go sightseeing with him, mind that he stops every once in a while to take pictures of the city UI:

• ticket-selling machines at the metro stop;
• bike-rental terminal;
• telephone booth;
• etc...

Besides that :) just a pleasure and a honor to have him hackercouching at my place.
