Wow really? I only see lag after I have over 1000 snow flakes on the screen, and I'm on an entry level amd cpu.
@Hibby: To change the background, just open snow.html with a notepad, and change:
background-image: url('snow.jpg');
'snow.jpg' is the file location, and since it's in the same folder, there's no need for like 'C:\blahblah\snow.jpg'
So basically, if you want to change the image, just drag the image into the folder, then replace snow.jpg with the filename, but be sure to keep the 's around the filename.
Or a real easy way is to just find a jpg file and rename it to snow.jpg, and drop it into the folder and replace the existing snow.jpg.
Also, you can change snow2.gif within ms paint, but as long as the filename is snow2.gif it's fine. you can point to a different file within snow.
