I see you did a little icm play so I'm going to push that a little further and have you do something totally abstract. It doesn't have to be using icm but that is one way you could play with it. I don't want to be able to tell what it is and you can use any technique you want but the result has to be abstract. . One example that I do sometimes that ties in with a long exposure would be while your a passenger in the car at night or in the dark try putting your iso low and your f stop very small (high #) and just move your camera around all of the lights. sometimes the result is interesting sometimes it's not. Just play with abstract however you want and have fun! Hope this works
Hope I was sure I was following you, but just realized I wasn't
... now I'm :)
