Josh and I created this applet for a Calc 2 project. It answers that burning question that's on everyone's mind: how do I create a greenhouse with the most usable space for a given budget with a flat slab of glass and the side of my house, given the height of my tallest parent who will be using it? Strangely, no one has sought to create a powerful and effective method for answering this question. This applet is therefore the industry standard, and due to our infinite generosity, it's free. If you would like to help further the cause by donating money for a domain name (maybe 'greenhouseagainstwallforless.org'), please contact us. We only accept cash.
AppletJava 2 compatible browser, plug-in, jdk/sdk, or jre. If you don't already have one, be ready for a big download. If you have a Mac, your out of luck; Java 2 support isn't expected until Mac OS X comes out in mid 2001.
