German female artist, specializing in fine geometric lines?

A few years ago, I came across the website of a German artist, female, who specialized in creating geometric artwork featuring very fine lines (think sweeping, 1pt lines). The only other things I remember are: 30ish in age, and had a non-standard German name, e.g. not something simple like "Anna Schmid". Anyone know her name and site?

Tools For the Spatially Challenged: Couch-Movers Edition

Wizards of Hive, Before I buy that 90" couch from a friend, how can I make sure I'll be able to get it up my L-shaped stairs? Sure, there are a lot of variables. But is there a tool or methodology for figuring this out ahead of time (presuming I know the depth and height of the couch too)? I don't think I have the cardboard to build a mockup. This couch is 50 miles away and can't be returned. Thanks!

Longitude lines in perspective, what shape are they?

I'm drawing/painting a globe (in time lapse, so the sun appears to rise) and trying to figure out what shape, exactly, the longitude (not latitude) lines are when a globe is flattened into a circle (I know I can just trace them, but I've gotten curious). So, the outermost longitude lines are tangent to the circle, they are half-circles, and the centermost line is a straight line from pole to pole, it's the progressively flatter curves in between that I'm trying to figure out. Do they have a name? Are they catenaries? Are they the curves of progressively larger circles? How do I construct them (easily)? Example image: HERE

What is the point at this!

Here’s a simple computational geometry problem. I am trying to figure out the value at an point of two line segments based off of the values at both of one of the segment’s endpoints. The problem is that I don’t exactly know the best way of going about finding the value at one of those points. Here is a reference figure. Given values (X_C, YC) = F_C (X_D, YD) = F_D How can I calculate the value of F_E, where F_E = (X_E, Y_E), where E is the point on the segment CD, where CD intersects with the line AB?

What was this geometric creature builder website?

Several years ago, I saw a website with a fun little flash or javascript applet thingy where you could build little tensegrity structure creatures, then have oscillating movements applied to the pieces, so that the structures would seem to "walk". I don't remember what it was called! From memory, one of the simpler structures looked sort of like this. What was it? Is it still online? [more inside]

Seperating Interlocked Rings

Formula to mesh two gears of arbitrary tooth count/position?

I'm writing a graphics app where I'm generating a simple gear transmission system with a variable number of gears each with variable number of teeth and placed at random orbits around each other. I generate gears in succession, placing and rotating each with respect to its parent/driver gear before moving on to the next. The problem I'm having is how to determine the initial orientation of each subsequent gear such that its teeth are properly meshed with that of its driver. [more inside]

Help me find this geeky kids' book!

I read a book sometime in elementary school (early/mid 90's) that I've been trying to find.
