Background for posters

Hi All,
was thinking we could use a selection of KGS backgrounds on our posters, similar to what Mitch has done in his montage, so that the posters all have a theme. I'm attaching 2 b&w photo/perspectives, feel free to make more (I just turned a photo to greyscale in photoshop, played with the levels and then used the filter 'find edges' and droped the opacity of the layer), or different ones for your posters, but would be nice if we can keep to the same style.
Is everyone OK with this?
