IMAGE DESCRIPTION: 


My girlfriend bought a pentatonic glockenspiel for her baby nephew and
instead of saying "how nice" I said "hey, even I could render that".
Thus originated my first submission - don't try this at home.

I added the chain to prevent the scene from becoming to idyllic ;)


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 


Originally, my main interest was to automatically derive the correct
length of the metal bars based on a specified pitch. This turned out
to be much more difficult than anticipated - just assuming a simple
1D harmonic oscillator yielded ridiculously long bars, even taking
into account that a glockenspiel supposedly sounds two octaves
higher than its nominal value.

After reading http://home.fuse.net/engineering/Chimes.htm, I finally
gave up, i.e. I ignored the absolute scale but continued to use the
relative lengths, just because they seemed about right. I learned
enough to know I don't want to be an instrument builder.

Apart from that, the geometry is very simple and not much worth
commenting on. I used predefined wood textures but still had a lot
of "fun" applying them. Also, I tried to simulate some kind of motion
blur for the mallet by using several partially transparent copies.
