Giving Leonardo the goosies

This page is currently putting up with massive transmutation and that is precisely why only the lonely code will have to make do. We will be back here faster than a Somalian with a free lunch voucher, but till then, Thanx for visiting this page. If you are a member of the Java-crazed community, you can still try out the code furnished here. Maybe with some divine intervention you might be able to get the drift...
