On 15th February the Reserve Bank of Australia revealed the design for the new $50 note to be released in October this year. It, like the current $5 and 10$ notes, features many security features. This includes some dynamic features in the clear panels that change as you tilt the note. As you might expect the RBA have made difficult to even copy an image to post here so I suggest you look further on the Reserve Bank Website.
