Thanks a lot!
I had a great day, my husband had prepared 30 presents for me and I had to draw 30 pictures to get them. It's in German, but if you want to have a look, here's a TUMBLR page: http://zibblenauts.tumblr.com/
The topics of the pictures were randomly chosen by picking 3 words from a box.
We always think of games like this for our birthdays, but this is HUGE. I have still presents left. MUST... DRAW... MORE....
I will be away until Monday because I'll have a party at my mother's house and most friends will stay until Sunday. But I will have a look at the contest.
