no, I'm using CATextLayer directly. It has a "string" attribute for NSString or NSAttributedString. And CA is available since 10.5.

>>> I am writing a small NSStatusItem which displays a NSString in the menu bar and supplies a series of NSMenuItems. As the text to be displayed is occasionally longer than would be permitted on the Menu Bar I would like to animate the text in a Stock Ticker style scrolling animation. Much like you'd see in iTunes when a song is too long to be displayed or how the modem connect NSStatusItem will scroll the words "dialing... authentication...". I tried to simply write text to the menu bar using a Timer writing one character at a time, but the result isn't smooth and due to spacing in between letters can be variable in how much it moves each iteration.
