Explosion alt

This is a photo i shot by pure chance during one of my walks through Hamburg searching for Graff/Streetart . I saw this window made of shatterproof glas at a shop . Something must have hit it very strong and fast ( like a bullit ) , so that this explosion-like markings emerged . I did not realize this attractive marks seriously until i worked it out on the computer , i was really astonished and enjoyed about the result . In this version i added a bit of blue colour .
Found this glas impact later [link] , this time i did know how to work it out - i think it's nice as well . The markings are quite different , another kind of glas - but a nice effect too ...
