I showed this at work and mentioned my Iphone app.
Someone said I have too much time to be writing IPhone apps.
I think of programming as an art form.
It can be a expression of thought, like painting, poetry, music or mathematics.
Every little piece builds up to the whole.
Sure, I could spend my time writting viruses, planting flowers or watching TV, but I don't do any of those things.
I like to think I'm a very good computer programmer. I believe that this is what I was born to do.
What else am I going to do with my time? 
This calculator looks great on the IPhone.
It still has a few of bugs in it, especially on devices that are weak in Javascript.
