Accidental holographic brush

I am sorry, is there an easy way to replicate this? I mean the holographic brush that just disappears into thin air. I was experimenting (hence the spinning canvas and everything else ) and i can't repeat this beautiful effect now

Ahahaha...you have discovered the "motion vector visualization"!
[v] toggles that. Just turn the fluidity up, fill the canvas and have fun. At some point this was meant to supply motion vector images, but it was highly experimental. So is hitting [Ctrl]+[d] during swirling, which would freeze the motion vector image and apply the motion to the image in a brief repeating preview. Strange stuff... ...I may pick up on that at some point!
In the meantime, just enjoy the weirdly pleasant experience!

Thank you so, so much! After i read your reply i couldn't stop playing with this amazing feature for a while, its hypnotizing! Thank you so much for making such a versatile software!
