Algodoo

That's some very good advice. Unfortunately, many users are young teens (or younger) who do not bother to read and learn about new things or ideas. I, for example, have written many tutorials (like this one) that explain good practices for making quality scenes, and not long after I posted those tutorials, I see more CRAP scenes being posted. It's down right frustrating, but the good news is, there are some people who appreciate this kind of tutorial, and who actually put into practice what they've learned. Algobox is used by many different people of many different ages, education levels, and general experiences. Some refuse to learn anything, but the majority who use and appreciate these tutorials make them worth doing.

Keep up the good work!
