on screen drawing with finger to search contacts?

[atown]

I saw a video where one of the android developers used his finger to draw a letter over his contact screen to filter contacts. He drew the lower case letter "e" and it went to his contacts that started with e. He used the same finger search to search music. Is there anything availible for droid like this, or does anyone know how to get it. It looked awesome, instead of scrolling or dragging grey square you just draw on the screen to filter.
