Inventions are drawn using a variety of examples, such as: photos of robots; or taking inspiration from the shapes and colors of birds or a tsunami barrier. Creativity is stimulated to conceive sketches for systems, installations or equipment. 
Depending on the group in which the lessons are given a choice is made to extend greater freedom - or by contrast - students are led step-by-step to work toward developing a variation based on one or another form of an invention.
The lessons are available to both adults and older children/teenagers.
This approach can offer the following advantages:
-
- Rapid discovery of the foundation for new ideas or new products and systems;
- Initiate, by use of improvisation, the invention and design of new products, systems or devices that make a contribution to the world, can improve the world or add something novel;
- the potential to discover additional problems that may pertain to the ideas previously conceived, whereby the invention can be improved.
The drawings are often a first step in development of an invention. Subsequent elaboration of these can be done on a computer, so the drawings are the beginning in the process of developing a new invention; then technology, measurement and models play a role. During the lessons we focus on the initial development of drawings expressing ideas, and how to work out those ideas in the form of sketches and drawings.
