Design a Website header having flash eff

I have a logo that I want it animated (having a flash effect) but without using adobe flash, rather i want it to be designed using JavaScript. then it will be used on a website header. i want it to have the same light abstract beaming from the logo in the same color (see attachment -intro2-) and with a light shine on the logo which will occur every 8 seconds. something similar to this logo (see other attached files) BUT REMEMBER NOT TO BE DESIGNED IN FLASH
