Ever wondered how they made that big billboard for Closeup? The one that holds the title of being the biggest photo mosaic. Well also wondered how they made it so I did some research and asked around.
My friend told me it's simple... you just need to download a software and use it to create a photo mosaic of your own. Don't know if this is the same software that they use but I asked for a copy of the software and used it to check for myself.
Above is the sample of the image... Pretty cool!
