I've been playing around with Photoshop, trying to find ways to create those reflecting, kaleidoskopic images without manually resizing and rotating images. This was eventually achieved by using embedded images - there is an origin file, one that is cropped to a triangle, one that reflects the first triangle and the final image, which combines the triangles in a hexagon. Voilá, now I only needed to swap the origin image and the final file would update. This enabled me to play around with many different source images. In a second step, I combined two images with different scales and even added some transparency.
This is the "Science" series.
Hey guess what: images from technology and science provide all the necessary details and colors for cool reflecting images.
