What does everyone think about making up name and car tags for all the attendees?

It may seem a bit hokey to have the "My Name Is:" tags, but it could be helpful in putting the forum name, real name, car and face together, especially someone like me who is moniker-challenged. Also, I've seen many individual pics of cars in large gatherings like this but have no clue who they belong to - last TMS day we had only 15 cars - we are already up to 26 with 4 months to go. I was envisioning something large enough on the vehicle to show up in an individual car pic...

Just a thought - any ideas or suggestions?
