Excel ART!

[JohnDove]

Found this so thought I would post.

You can create a mosaic in Excel 2007 from any image. The cells background colours are set to form an image.

And its free for personal use!

Some alternatives using native excel, no .net stuff required.

Only tried the first one and it seemed to freeze on my image (that or it was taking a very long time to analyse the colours!!). I'm using vista and excel 2007.

I might have a look at the other later.
