I find that having hard-to-read writing is a source of creativity in itself, so that when re-reading what I scribbled yesterday, many other, unintended interpretations come to mind.
For people who find having ideas is hard work, there are now many tools which pump out random combinations of words to help unstick the mental gearwheels.
Now it’s also easy to make a computer font from your hand-formed characters.
Today’s invention mashes these together so as to create and printout a list of word triplets in one’s own semi-legible handwriting. These can then be viewed later and are a surprisingly suggestive source of novelty.
