I picked up this lighted top at Christmas, thinking it would be fun to play with in front of the camera. And it was! I got the room real dark, and took a bunch of images, spinning the top at various speeds to entice it to walk across the frame. I particularly liked this image because of the slight touches of green and blue at the edges, accenting the thick center area of red and yellow.
This image was taken with my Canon 7D and 24-105/4L lens. Postprocessing was done in PhotoShop, with a little High Key filter from Nik Color Efex Pro thrown in for good measure.
