Have you looked at Smartsockets yet ? They are flexible and carry many
animations and special effects. One required per tube.
I'm currently working on a four tube IV-17/IV-4 vacuum fluorescent 16
segment display Smartsocket, in case you were looking for mini (and
cheaper) version of the larger FLW
Details are at

Feed them with ascii message strings and watch them display the
message. Simple
