Kaleidoscope!

It's been rainy and chilly all week so I've been spending a bit more time than usual in front of the computer.
I am really no expert but I do like randomly finding out what the various tools etc actually do!
To my excitment, these images magically appeared when I layered various pieces of art on top of each other,
The thing I like the most is that they have a distinctly 1960's/70's feel, I think it's the colours!
what do you think?
