How to visualize touches with android (Nexus One)

Do you know if there is a tool/setting that allows me to visualize the touch events while using my phone? I would like to use it for a usabilty test.

There is a tool for the iPhone that does exactly what I need (It´s called DisplayRecorder) In this video you can see what I mean: http://www.youtube.com/watch?v=WGOrkDxgMME

I didn´t find a similar tool for android. I´m开发者_运维问答 not sure if it works with the dev tools setting "Pointer Location" - my Nexus One crashes when I try to set it. Does anybody know if this works while using the phone as normal? In terms of a layer on top of the normal application?

Hope someone can help me! Thanks in advance!

I used a small "joke" application creating electrical sparks where one touched. That's probably not really what you want, but maybe you could craft your own app using the same principle: a transparent overlay, registering touches and displaying a haircross where they are detected (and possibly showing coordinates in a textbox or something).
