It's fun, particles always are

.
Keep at it, try doing it again now that you know how to do it. See how long it takes you, perhaps vary some of the forces. See if you can make the particles create a new word after they have disintegrated the old one.
Perhaps try a very subtle approach too… have the particles “peel” off the surface and slowly float downwards like leaves or snow.
Good stuff for a first run! Enjoy it lots more!
