Programming demotivators

It struck me on demos, and I decided to share my "works of art" with the habra-public =)

Careful traffic!
We'll see…
PS Some photos (not demos, I did them) were found on the Internet, please, if possible, report on their authorship.

UPD: I have already managed to criticize, and this is right, but in my defense I want to say that these are my first demotivators, and next time I will definitely take into account all wishes.
UPD2: Transferred to Humor.
