We are a not-for-profit organisation and are very appreciative, grateful and thankful to http://highslide.com for their generous licensing policy of allowing not-for-profit organisations to use their wonderful product without charging a fee.
We cannot see outside what we are not inside. The universe is to us what the huge engine is to the miniature engine; and indication of any error in the tiny engine leads us to imagine trouble in the huge one.
