More or less... ;-)
Making a special kind of box is very easy, just have a look at the simple
boxes like image or colored-box for instance. But in your case you don't
need to make a new kind of box, just use an user-drawn-box and provide the
drawing function. Now it's using this for a logo that seems strange to me.
Generally you place the logo at some fixed places on the page, not in the
text. Anyway once you have a draw-logo function you can use it in a
user-drawn-box as well as using it directly.

OK I will have a look at that.
