I love this Program!!!! I'm a Mathematics teacher and I use it all of the time when I am assembling test papers. Thank you for making this available!

It would be even better if I could do trapezoidal prisms, and if the perspective could be standardised to isometric.

The hidden line feature is the best, and the main reason I favour this software.

This is excellent stuff! I've registered and used it for about 20 vinyl LP's or singles so far. You can set it to process with just the noise that is being removed being outputted to your speakers. You will hear no music, but lots of LP noise. That's what it's getting rid of! I have now abandoned other products that simply made everything in the file sound weird no matter what settings I used. My LP recordings aren't perfect, but they are pretty good. The faults still audible are caused by aging and original manufacturing quality. (80's LP's made in Australia were of much crappier quality than UK imports!) They seem to be distortion and oversaturation issues rather than mechanical noise.

Wow! Just what was needed! I'm really glad it's free. Not because I'm cheap, but because this is the sort of thing that I don't need often enough to justify spending from my small budget. I would just do without it. So I'm very grateful.

Hello, rest of world here. Why did I have to download, install and go to the website to find this out?

"We currently provide data for Canadian and U.S. postal codes only."

It's this sort of 'oops' that makes some of the US population look so narcissistic to the world.

This is a great tool for educators and others just interested in the properties of the atmosphere. Although what it does could be communicated well in a more graphical way (sometimes, though, people can't interpret graphs well and then the usefulness is gone), it allows the user to interact with the numerical values and see the results. I especially like the speed of sound part - great when teaching about Mach values. Atmosculator could do with a preference setting to use SI units with just one click and an alternative input method (maybe sliders) that allows you to step the values up with clicks. It's still a great program for using but hiding equations.
