I ran across this and while I’m not sure it can be considered “useful” it might be so I thought I’d share!
It’s definitely fun
It lets you type in any words, and then it puts them in a bunch of different moving configurations, either pre-set from the menu on the right, or modify the parameters from the menu on the left.
Well that’s impressive! I can see how some of them could work on the GF, if you type something in and can make a screenshot to capture a particular moment in the transition that you like. Then turn it into a design to engrave. Will have to play with that!
