Happy smiley face constructed out of urine samples in plastic bottles. Brave scientists have to stay positive while testing the health of other people.
This picture was created for my precious friend epSos.de and can be used for free, if you link epSos.de as the original author of the image.
This creative art was created by the happy employee of the month. It is very motivating for the other scientists in the lab.
The red eyes of the smiley face are the urgent samples.
