The company I made this for is a cross-media production company. I got the assignment to create a christmas card. For a cross-medial company I found it a bit to easy to go for the standard group-photo-ish idea. Since they do a lot with video I came up with making a small video card aka a lenticular card with all the colleagues interacting with the company-logo.
It was a fun experience during the photoshoot, with everybody participating enthusiastically, and also quite daunting with me being in charge of the whole bunch. Eventually we pulled it all off, and I'm very happy with the end result. (the video doesn't really do the card justice though,... o well,... use your imagination.)
