Starry Night

I love this Scratch project, created by Scratch user nikita_i, because it shows how a beautiful and rich animation can be created with just a few Scratch commands (puzzle pieces). In fact, this project involves fewer than 15 commands! If you want to try creating a project like this, there are some hints below.

Hints!

  • There are 45 stars in the sky. Each star has exactly the same set of commands, in the same order (script).
  • Each star begins its flight at the right side of the screen and moves constantly to the left. When the star reaches the left edge of the screen it jumps back and starts its journey again from the right.
  • Each star’s height in the sky, brightness, size, and speed are numbers chosen randomly. These numbers change each time the star makes a journey.

How did Nikita do it? Think hard!

If you’ve thought as hard as you can, you can see the answer by downloading her project from the Scratch web site at http://scratch.mit.edu/ (login required).
