This "glow swirl" effect is doable via drawing a flashlight really fast at night and then taking snapshots of its path (we used to draw fun doodles and write our names in "glow" lighting with our roommates in college). However, since such night snapshots are hard to capture on camera, Photoshop can do you for you instead in far less time.
This Adobe Illustrator/Photoshop tutorial shows you how to make swirls with a glowing effect.
