Big collection of pen drawings, each one being exemplary for being exceptionally beautiful or complex despite being produced by no more than 15 code blocks.

Click the green flag to run the project, then click the green triangle to start the show. It takes 9 minutes to see them all (3 minutes on turbo). Use the purple buttons to fast-forward to a specific drawing.

Please feel free to comment which drawing you like best! Each drawing has a number, displayed in the top left corner.

Notes and Credits

All the pen drawings in this project originate from a programming challenge, announced and judged by Keith Enevoldsen, spring 1997:

"Write a Logo one-liner using 15 or fewer words, not counting square brackets and parentheses, to produce the most beautiful, complex, and interesting picture."

All artists have been credited in the project itself.

The scripts have been ported by me from source code written in the programming language Logo, published on the challenge's web site:

I had to leave out some drawings because they relied heavily on 'pen reverse' (painting with the pen turns white areas black, and black areas white) or other features not supported by Scratch. In other drawings I made minor changes to achieve a certain drawing speed or to make the drawing fit on the stage.
