Extreme? I don’t know. Novel, definitely. Extreme-apps.com has just put up Shake-and-Save on their website. Shake-and-Save lets you simply shake your Windows Phone and it will automatically do a screen capture and save it to in the format of your choice. This can be pretty handy for folks like me who do a lot of on-device screencaps.

And I love the warning on their site: Hold you phone tight. We are NOT responsible in case you drop it.

Extreme Apps says it specifically supports these devices:

• HTC Touch Diamond/Pro
• HTC Touch Diamond2/Pro2
• HTC Touch HD/HD2 (LEO)
• Samsung OMNIA (i900)

I’d be curious to know if it works on any accelerometer-enabled Windows Mobile device – feedback anyone? My Xperia doesn’t have one. Download it from the Extreme-Apps.com website and give it a try!
