Hi,
I put the 4 Skylines together and measured the outside dimension of the Skylines measured from the outside edge of the outside cubes. There is a small flange or lip on the skylines that create the small gap you see when you put them side by side(I subtracted this dimension so the pic would fit exactly to the size of the cubes). I found the pic on ShutterStock.com and paid @ $2 to download the highest res I could get. Took the file to a local place here in Atlanta that can print large poster size pics in high res. The poster was around $50- 60.00. I then took the measurements of the cubes(they are not square which makes it a pain in the butt). I flipped the poster over face down and made the lines with a straight edge. Each Skyline has 156 cubes so that is quite a few lines to make on the poster. I then labelled each square(1-1, 1-2, 1-3, 1-4, etc.... 2-1, 2-2, 2-3, etc, 3-1, 3-2, etc. Have to do this so you know what order to put the small sqaures on the Skylines in the right order. I then bought about 20 rolls of scotch double sided tape and proceeded to tape each square one by one on the cubes in order to recreate the picture. Oh, I forgot that I had to paint the skylines black first. Not a easy task unless you have access to a decent sprayer. I tried spraying first, but did not work so well. Ended up getting a triangualr sponge brush to get down inside the cubes. I think I spend at least 2 14 hours days to complete including the painting. If you have a decent spray gun and know what you are doing, that would save some time.Please send me some pics when you are done

. It looks really cool in the end. I am getting ready to put some led lights inside the edges to add a background lighting effect. I will post pics when I get it done. Thanks for all of the compliments!
