That 'DOH!' moment.

This life size animated greeter at a local hospital was clever enough. Rear projection and all that, it was quite eye catching. Sadly however the Serco and NHS badges on her shirt are the wrong way round. They should have 'mirrored' the video!

Not that I'm that bothered. It's not like OCD or anything, but I did have to sneak around the back to watch the message the right way round.
