What can I do with these LEDs?

I found this flashing LED thing and I was wondering what I could do with the LEDs and the components...

The LEDs are connected to an externel power source which is a european 220V plug.

As I can see, you've got some modules with different colors, right? If your skills in electronics are good enough you can do many things with these components. My first thought was a disco light, which is controlled by a frequency-seperating filter :)

Same things you can do with any LEDs...
In this case, extreme measures must be taken - attach them to your (author's) face.
