I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in its classical Greek synthetic form and in its more modern analytical/transformational form.

No, can't say I have. But it doesn't sound bad. I like all the individual ingredients you mentioned.

I want to know what you ate to change your mood. I could use a little something that would excite my interest in some of the current crop of questions. As long as it not an illegal substance, of course :-)
