3 flash SWF scenes with interactive animations/particles

Industry: Technology
Design details: 3 of the below 5 x SWF Flash scenes required within the next 5-6 days (as of 14/04).

1. Elongated re-sizable 5464 x 768 background of city rooftops with balloons floating up. On rollover (when touching a balloon) they pop. There'll be background looping audio and a pop sound which we'll provide alongside the background.
2. Elongated re-sizable 5464 x 768 background of an woodland scene with trees. On rollover (when touching any one of 3 trees in the scene) superimposed leaves fall off the tree and float to the ground. There'll be background looping audio and i'll provide the background.
3. Elongated re-sizable 5464 x 768 background of an underwater scene with fish swimming by. On rollover (when touching a fish) they dart away or gather around. There'll be background looping audio and a splash sound which i'll provide with the background. The fishes' reaction can be simplified if its too complex.
4. Elongated re-sizable 5464 x 768 background of a sky scene with a flock of birds flying around randomly. On rollover (when touching anywhere) they flock around where has been touched. There'll be background looping audio and a splash sound which i'll provide with the background.
5. Elongated re-sizable 5464 x 768 background of bubblewrap. On rollover (when touching anywhere) a bubblewrap segment pops where has been touched. There'll be background looping audio and a pop sound which i'll provide with the background.

All designed to a good/realistic standard with a hidden mouse cursor.
