HWÆT WORLD: how should I generate and display graphs of prime numbers?

I haven't programmed much for years. Now I want to play around with different ways of visualising the Ulam Spiral and I'd like suggestions for the right tools to use. I want to generate or load arrays of (say) 100,000 numbers, depict them on a 2- or 3-d graph, and move the lighting and/or viewing angle to give an impression of depth. Details inside. [more inside]

Measure how noisily I sleep :-)

I have a pretty bad case of night terrors. I am turning to the hive mind to help me identify a cheap and effective solution/device that will record the times when I'm audible throughout the night. I don't want to know what I'm saying as it sometimes freaks me out (nothing scary, I'm just weirded out by listening to myself yell/whisper subconciously). So a tape/voice recorder is out of the running. In short, I need to know what time I make noise, and maybe a little squiggle or number on a piece of paper/read out screen letting me know how loud I was relative to the rest of that night (I'm thinking of the needle that scrbbles on rolling paper with a time stamp next to it like a seizmograph). Any suggestions? This can be hand made or purchased as long as it's not too expensive :-)

"Bars that get shorter over time"?

In the Sims games, each Sim has a set of bars representing their needs that get shorter over time. Each bar gets shorter and shorter until the need (e.g., hunger) is met. I can imagine the same kind of bar graph being used for a gas gauge or a visual representation of a bank balance. Does that kind of graph/gauge have a name?

A question about graphs

On blank graph paper, what is the mathematically proper name for any random line you see on the page? It wouldn't be "coordinate" since that refers to the line's value. It wouldn't be "grid" since that refers to all of the visible lines. It wouldn't be "axis" since there can be only one in each direction. I'd also be cool with the name for all of the lines (as a set) that are parallel to one another. Thanks!
