An immediate response came from a zentangle warhorse. A page was created HERE (inspired by my idea) for people to download ready-made strings. The difference between our ideas is that mine requires and triggers the creative invention of the doodler from the very start, whereas downloading someone else's strings has already relinquished part of the process - it's a tiny bit like painting by numbers! The intentions of the ready-made string are not known to the recipient (downloader). That may, or may not be an advantage.
The drawing I like best of mine this week is this one:
