New SGN site design element

The SGN site (http://solgenomics.net/) just go a lot prettier - and hopefully more functional for users as well. We have added some beautiful graphical menus, with an example shown in the picture below. Note how the agricultural field (how appropriate!) gives a 3-D impression with a perspective whose vanishing point coincides with the 'Genes' icon. We felt that the most important menu item should be at the vanishing point, if only because Leonardo daVinci put Jesus in the vanishing point in his famous last supper painting. In design questions, it's always good if you can side with someone like Leonardo! Thanks to web designer Camilo Rosero for this beautiful design!
