Every year, it seems like there's a new pattern. The newest one we have is a happy face. We're trying to send a 2, an 0, an 0 and an 0 up. The pattern shells are one dimensional. Depending on the way they orient, the main viewing audience is going to see it, but somebody else may not see it.
Practice is difficult.
Our rehearsals are basically the last show we did. There are some remote desert areas that we use. Every year we get new products in from suppliers. We'll take a bundle of those out and launch them up to check how the shells are going to function. We sometimes find a shell that is malfunctioning consistently.
