I dont know if this have been published before… but I got a beautiful bounce effect using simple trigonometry. 😉  
In the attachment, the A value controls the bounce increase in the first launch (The amplitud of sin function), The i increment defines the function period (T) the bouncing times…thats all.  
Its easy and useful and itss functionally on MX and MX 2004…No problem 😛  
Tell me what do you think.
