This is bonkers! Not sure what to use it for yet, but it's fascinating! Simply type in the name of a topic area or 'tag' in the box, and it collects images into the middle. Then you can click on one of the planets and all the images are pulled down onto it (like with gravity!). I typed in sports and it was brilliant. Like I said: not sure what it can be used for yet, but someone will like it I'm sure!
