Use TURBO mode to see the demonstration pattern. (Press the <Shift> key and click the Green Flag for TURBO mode). The "1 Line Challenge" is to produce an interesting pattern on the screen using only one line of code to calculate the color of each pixel. You may only change the "set pen color to ..." line in this project. Please put your remixed "1 Line Challenge" Projects in the Studio https://scratch.mit.edu/studios/2825709/ If you just had to break the rules please put your "Not Quite A 1 Line Project" projects in this studio instead https://scratch.mit.edu/studios/2825759/ "See Inside" for more Rules, Rewards, a Short Tutorial etc.
Imitation is the sincerest form of flattery. Thanks to MartinBraendli2 who did the harder Swiss Flag to copy from. A circle is much easier than a cross. I managed a plain Japanese flag, but Martin had to show me how to get the colours right for the ripple! Thank-you!
