Do you clap in church? I've been with clappers and non-clappers and wanna be clappers too. :)
The last group are the most fun to be with. Unless your the song leader of course!
Today I found a cool little app, but it's not free. $20 from http://www.theapplausemeter.com/
You can hook it up to your laptop and then have your own applause meter at church. This has got be useful for some youth event or something doesn't it? Let me know if you have any ideas how you might use the Applause Meter in church.
