Slosh
How to be creative - (i) Randomised input: Triangle-person is looking at a tree, with arrows coming off the leaves, directed at their eyes.
(ii) Novel neural sloshing: Triangle-person’s brain is shown. The arrows point from the eyes to the brain, and inside the brain there is more arows swirling all about.
(iii) Creative output: Triangle-person is now drawing on a piece of paper. The arrow is pointing from their brain, through their hand to the pencil they are holding.
I find that staring at something random helps a lot in getting new ideas and connecting old ideas in new ways. This can’t be something that I know like the inside of my own house.
A bit of shrub is good, as it often moves in the wind and changes over time. It can be anything that introduces some kind of variety, and it can be through any sensory input. Smell might be hard (a trip to rubber boot factory?) but sound is easy: just use flowing water - also known as a shower.
Then I just need to let it slosh for a bit, and there you go! New ideas.
(In reality, it’s of course not that simple, but for the purposes of a comic it’s a good-enough approximation!)
