Well done. :) The sine curve is a nice touch.

If you're planning to continue along these lines, here's something that might help you. It's a formula I worked out for transitioning any linear number value (X, Y, W, H, alpha, etc.) such that it accelerates at the beginning and decelerates at the end:

Code: Select all

Xi + ((Xf - Xi) / 2) + ((Xf - Xi) / 2) * sin(pi * (t - 1/2))

(Xi is the initial position constant, Xf is the final position constant, and t is the current point in the progression, between 0 and 1. By increasing or decreasing t at a constant rate, the formula evaluates the actual position over time.)
