What are some ideas for how to add feedback to a Checkbox input?

The normal use of a Checkbox is fairly straightforward. You click the box and a check appears in the box. You click again to remove the check.

I'm looking for a way to add feedback to the clicking of the box. My current idea is that you would have to click and hold down on the Checkbox and a progress bar would pop up and begin filling up. Then the item would only be checked after holding down for a given period of time, giving a sense of completion.

Sorry if this question is a bit vague, but I'm looking for not only implementation advice, but also any other ideas of how to create a sense of completion and feedback from clicking in general.

I know we're not exactly using DualShock controllers to do our clicking on the web (so haptic feedback is probably impossible), but I'm just looking to experiment with w开发者_开发问答ays that we could simulate something similar.

I like to use highlight to let the user know they clicked something or something happened

$foo.effect('highlight',{'color':'cyan'},300);

using jquery ui effects
