Here is a great abstract keynote theme for your collection the Pink, Purple Celestial Swoosh theme is designed to fit many environments. It will stun and amaze, and help to hold your audience’s attention. Use the for business, school or even church events or functions. This will surely enhance your presentation. I’ve edited the master slides so that each one you want to use should have the image in the background.
This image I believe is an iPhone 6 standard background, so, it has wide appeal and should be largely recognizable.
Try it out at you next board meeting, in your next lesson or at your next Happy Hands Club meeting! Enjoy!
