Another batch of prints arrived from Shapeways yesterday. The Alien Egg spherical function printed particularly well, as you can see from this print/render comparison.

Info about my lecture/lab/tutorial times for next academic year have been posted on my teaching page. Getting prepared this early is pretty organised for me (although all still subject to change).

Shapeways returned my very simple (two spheres merged with two cylinders) spinning top, and it works alright (maximum spin so far is just over 1 minute!). I've updated the description on Shapeways with new photos and such, so it's now available for anyone to get hold of.

There's a photo of the 3D Lissajous prints that recently arrived from Shapeways along with a new render on the Functy blog. The prints have come out really nicely, and are currently performing well as desk ornaments!

Now sporting its new name, along with a bundle of bug fixes, a new version of Knot3D is now available. Knot3D is an open source (MIT-licensed) Celtic knot rendering program. As well as traditional flat knots it'll also create full three-dimensional cuboid knots, which can be output as mesh files for rendering or 3D printing. Installers are available for Linux and Windows (as well as the sourcecode if you're using something else).

Knot now has a new name: it's now called knot3d. It's not a massive change, but an important one since it turns out there's already a (very different) Debian package called knot. The new name is to avoid it clashing. Thanks to Daniel Matthews for highlighting the issue!
