'Hello World!' - Mural paintings in the new Pavilion Q of the Faculty of Information Technology at the BUT | Robert Gallo

The development of the HELLO WORLD project for the Faculty of Information Technology in Brno took one year and two months, beginning with the first contact with the architects and ending with the reception of the painting by the investor.

It took 15 days of actual work on the painting, 5 days of retouching, 6 helpers, one speaker, gallons of coffee and acidophilus milk (preferably the strawberry flavour) and 6.5 tons of cheese and salami pizza. Added were the smells of acrylic paint, wet concrete and the canteen next door.

"Hello, World!" is a small computer program used as a prompt in teaching programming. It is the first program written by most of the students. The painting is actually a transcription of the source of this program (realised using a geometrical font based on the cycle of paintings called The Score) in the "Perl" programming language.
