email addresses: @-sign needed

[N. J. A. Sloane]

I thought it would be easy to find gif files
for "at" and "dot", but I can't seem to find them on the web.

Can anyone help?

What I need are two gif files, one for the @ symbol,
and one for a "dot" or "period" 

They should be the size of "at" and "dot" 
as they appear here @ @ . . . @ @
so they will look normal when viewed as part of text

Thanks!
