  • The Travelling Salesman Problem – A challenge for Scratch-Tinker

    Imagine that you are planning a trip through several cities and want to find the shortest route to visit each city exactly once. What at first sounds like a simple task is actually one of the most famous puzzles in computer science: the Travelling Salesman Problem.

    But don't worry, you don't have to be a math genius to face this legendary challenge. On the contrary! We grab our colorful blocks in Scratch and show how to solve this complex problem in a playful and creative way.

    In this article, we take on the Challenge and tinker together on a solution. Are you ready to show the traveler the most efficient way and dive deep into the world of algorithms? Then let's get started

  • From AI to Plot – Motives as Vector Graphics

    In this short guide, I'll show you how to create your own motif from a simple text input (Prompt) in a few minutes and use Inkscape – the free open source solution – to use it as a clean, scalable vector graphic (SVG/PDF). We generate the image via AI, transfer it to Inkscape, vectorize the appropriate contours and optimize edges and size - ready for plotters, foil stencils or screen printing.

  • Clones in Scratch – Many objects, one idea

    In Scratch, clones are exact copies of a sprite that can behave independently. They make it possible to create many similar objects (e.g. Enemies, stars or particles) without creating your own sprites multiple times. Clones save time, simplify code, and make projects more powerful — ideal for games, animations, and interactive simulations that require the same elements in large numbers.

  • Gemeinsam kreativ – Kollaboratives Arbeiten mit Scratch

    In this project we will draw a house with Scratch together, with different pens designing different elements. One pen will paint the house itself, while another pen will add the door. The stage plays a central role by setting the global variables x and y when clicking with the mouse. This information is then sent to the other sprites to work synchronized and cooperatively. Let's get creative together and create our own digital house!

  • Binomial coefficient as a marble run – Mathematics to touch

    Welcome to "Binomial coefficient as a marble run – Mathematics to touch”! In this article we present an innovative marble run based on the modular system Marble Castle. This special marble run works similarly to a Galtonboard, but the marbles do not fall by chance, but always alternately to the left and right. This results in an exact binomial distribution that vividly illustrates the concept of Pascal's triangle. Immerse yourself in the world of mathematics and discover how playful learning works!
