30/60/144 individually-controllable LED pixels on a flexible PCB,

It's completely out of control and ready for you to blink,  

And an extra heavy flex PCB in white & Black version,
The digitally-addressable type of LED strip. You can set the color of each LED's red, green and blue component 

with 8-bit PWM precision (so 24-bit color per pixel), 

Regarding it's flexible PCB material, you can cut this stuff pretty easily with wire cutters, there are cut-lines every

LED. Solder to the 0.1" copper pads,

You can also connect strips together to make them longer, just watch how much current you need.
