Imagine a red balloon tied to the doorknob of your hotel room. A balloon on a string looks like a number 9: now you can remember your room number. This is how a simple memory system works. The problem is, the system only goes up to 10; number 9 may look like a balloon on a string but what does number 23 look like?
When I found out that the Earth tilts at an angle of 23 degrees I was inspired to find images for numbers 1-100. My own system was born and a whole world of knowledge started opening up. Then my friend Tine said: ‘I think this could be a game…’
