Simplest way to make an LED flash (part of) the Fibonacci Sequence? Answered

I'm trying to figure out if I can make one (or possibly several) LEDs blink maybe the first 15 Fibonacci numbers. Wonderfully awesome (but unnecessary) would be if I could also have it emit a sound (loaded from my computer) at the same time, in sync. Would something like a 555 timer work for this, or is that silly? Would that also drive the audio? What is the simplest way to do this? My experience with electronics is very, very basic - nothing beyond playing with LEDs, soldering/unsoldering components, wire splicing, a super-simple Jacob's ladder, etc. Is this project too advanced for the time being? I'm not asking for the schematic to be built for me, just some direction - I don't know what I'm doing here. Help?

spiral clock hands

I want to make a desk clock as a small project for myself. What I am looking to create is a slim clock with a spiral hour hand. The time would be told by graduated marks on the back-plate i.e. as the hour hand turns, the spiral increases and the correct hour is reached by the spiral, hard to explain, can't upload a photo as instructable server maintenance is under-way, hopefully I'll be able to upload the brief sketch I did in paint which might help!! What I am looking for is suggestions on a material which could be used for the hand, it needs to be thin so as to make it as easy as possible to tell the time and also strong enough not to distort under its own weight. Haven't decided whether it's going to be a normally incrementing spiral or a Fibonacci spiral (or similar logarithmic spiral)
