Windows and OSX on the same desk top

Since I've had so much trouble with all these supposedly 'easy ' programs such as Parallels, and wine doesnt work right (butr wine wrapper sure does..)..
I fooled around with virtual Box.. and now with the click of an icon on the taskbar, i've either got the windows desktop icons, or the mac one.. both of the taskbars are always there in any case, transparently..

I have it in an animated GIf, but it's such a pain trying to add one to blogger, it appears you need a photobucket account and it's fu*ked.. it keeps saying my 'zipcode' is wrong.. stupid piece of shit.. we don't *have* zipcodes in Canada..
Here's my desktop.. it would be a lot easier to understand if it were an animated gif as then you'd see that the desktops are perfectly aligned...
