I have an ongoing project i work on in my free time similar to this.
Here is a link to Tundra Geeks website where i have some videos, even though you can't see them too well.

I think i have made some minor mods to the code since this, i have some functions in here that weren't even being called at this time.
The LED's are in each front door handle of my truck, each rear door handle and on the passenger and (soon to be) driver foot well.

I was also delayed because customs held my bliptronic leds for a couple of months.
