Welcome to the sq3 website. To say hi, send an email to [tim.hutton@gmail.com].

News:

• New: Working for Microsoft Rare, on Kinect data. It's a contract, so I'm free in September 2013. [CV is here][LinkedIn profile].

• Having got interested in reaction-diffusion systems I've been finding a lack of source code for running them, so I've started the [Ready project]. Below are two renders of the Fitzhugh-Nagumo model in 3D, with the 'tip-splitting' parameters.

• The [Rule Table Repository] continues to grow. We need to think carefully about the rule table format, to avoid hitting problems later.

• Golly is an amazing program. I've managed to implement Codd's fabled self-replicating machine and get it to work. Details and downloads here: [1]

• I've put a bit of work into a demonstration implementation of lattice gas automata, for fluid simulations in a CA. See the [Lattice Gas Explorer], and here's an image:

• von Neumann's self-reproducing machines have become a reality, thanks to the Golly people porting them to the hashlife algorithm. I've put a new page here: [2].

• My alife work is concerned with implementing evolution. Somebody just announced a $100K prize for doing just that - but is it all that it seems? Here I have an open email discussion about it with the prize sponsor: EPrizeDiscussion.

Coding:

Here are some open-source projects I've started:

[Reaction-Diffusion]	A cross-platform implementation of a wide variety of reaction-diffusion systems.
[Lattice Gas Explorer]	A cross-platform simulator for lattice gases, with an emphasis on being a tutorial for learning about them, and about their implementation.
[Slinker]	A cross-platform Slitherlink puzzle generator and analysis engine. I haven't touched this for a while. I get my slitherlink fix from [Kwon-Tom Loop].
[Organic Builder]	A fun applet that lets you explore the rules of artificial chemistries, and challenges your skills at organic programming. On the back burner at the moment.
[Organic Builder in Flash]	A port of OB to flash applets. I really should work on this.
[PowerCrust]	My VTK port of the powercrust algorithm.

Here are some open-source projects I've made contributions to:

[Golly]	Cellular automata. Astonishingly quick in some cases because it uses the hashlife algorithm.
[VTK]	The visualisation toolkit is a cross-platform cross-language library for 3d rendering and visualisation and mesh processing. Has some interesting algorithms.
