I really like this. There's so much to look at and explore visually! Someone may have already told you but I couldn't take the time to read through every single comment so far: if you want to make the white transparent so that it matches the background of ANY webpage you display it on, open it in Photoshop. Turn off the white layer so that you get those crazy transparent squares in the background instead. Go to FILE. Go to SAVE FOR WEB AND DEVICES. In the upper right section of the dialog that will open, select PRESET and pick PNG-24. Make sure the "transparency" box is checkmarked. Save. Voila, transparent web-ready background.
