As someone who works in K-12, allow me to familiarize you with the "Oh My Freaking Goodness!" initialism.

agreed. This is really cool (and simple too)

Also, how hard would it be to set an initial state of our current solar system? Teachers could set up scenarios for students to interact with, and allow students to collaborate.

Maybe as simple as an output/input of textual data for saving & restoring state? i'd love to try model our current solar system, and see if i can get something to mars with just an initial trajectory.

see:

The scale of the Solar System would require you to visualize the bodies as much larger than their true size in order to see everything on one screen. If the Sun is 1 pixel, all other bodies are way smaller than a pixel, and Neptune is 3000 pixels away. And of course, you'd probably want to speed up the simulation speed.

Maybe I should clarify that I didn't make this, I just stumbled upon it and thought other people would also get a kick out of playing with it :)

There exists a similar if not more robust gravity simulator that's available for free to schools. It's called Universe Sandbox. Here is a link for instructions on obtaining educational licenses. http://universesandbox.com/blog/category/education/

Just out of curiosity (I'm not offended by OMFG myself), I'm wondering: would "ZOMG" be ok?

Its a shame that a simple button label would be the cause of an education tool to be rejected... sissy-state for the win!

OMFG is not a standard abbreviation. If you are making a tool that can be used worldwide, best to stick with words and slangs that are universally known.

Moreso, best to stick with terms that are acceptable to people of all cultures and backgrounds. The word 'fucking' may be a light-hearted slang to a 20 year old american, but it may just be offensive to someone older living in the UAE.

Professionalism, though not perfect, does in fact help in making people from various background agree and understand good ideas by being austere, simple and well-defined.

Even with the USA "fucking" would be unprofessional!
