I really like what I have done here and I think it is my best piece of work on inkscape...so far!

This picture on the right is a repeating pattern. I made it by using the cloned tiles option, so this created 9 tiles aboce and next to and above it. Whatever you did to the original tile would happen to the neighbouring ones too. Even when you overlapped the tile, you would only have to put the same object on the opposite side of the tile. This gives such an effect that you can't tell where the original tiles were in the first place. I made the repeating pattern out of little earth globes and light bulbs to represent that we should be more aware of how energy saving can make a difference.
