Welcome to: Scratch Resources

Added a scratch version of the Rainfall Problem, but currently it does not check that input is a positive integer, which is part of the specification.

Scratch is a programming language, that makes it easy to crate your own games and animations.


Snap! formerly BYOB is a drag and drop programming language. It is an extended reimplementation of Scratch - using Javascript and running in your browser.

Its good to see an implementation that isn't dependant on a close source implementation. I would recommend snap over scratch partly as it works in the browser, but also it does not rely on flash which is a security threat.

This page lists some of my scratch files:

The shapes.sb file is for drawing simple shapes, in the logo approach, it currently only draws a square, triangle and hexagon, more shapes to follow.
