define your accentstrip as -2 (assuming 2 pixels) and use style_pixies matching the indexed folder in /extra/PIXIES where the sequence is defined with the GraFx engine
You'll find examples in the manual explaining how GraFx work and the default package has a few examples as well. Basically, you'll just draw a BMP that contains the animation, and it will be a 2 pixel wide picture times N lines (= N steps of your blinkies animation)
