This was a general discussion meeting.

* Vish presented Perlin Noise in Clojure
I've put together a small program in Clojure to demonstrate Perlin
noise, a particular variety of random noise that is commonly used in
3D graphics for generating textures, heightmaps, ocean simulations,
and so on. I'd like to show how the program is constructed and I've
got a simple graphical demo of 1-dimensional Perlin noise. Nothing too
fancy since I haven't gotten into 3D graphics in Clojure yet.. but the
math for generating the noise signal is perhaps more interesting.
