Probabilities: Coin Flipping

Simulation of flipping up to 10 coins, in which each coin is not necessarily "fair" (i.e. has 50/50% chance of landing Head/Tails). Use sliders to select the number of coins and the probability that each will land Heads (H). Use buttons to simulate a single flip, automate the whole flippin' process, reset all coins to be fair, or restart to 0 trials. Beware that after several hundred trials, the app may start to drag. Inspired by text/email exchange with friends, in which one of them pondered how an unfair coin would change the normally-normal distribution. Are your friends as cool as mine?
