Yes, that's an excellent idea. And in the north of course a penguin
colony ;)

I though about this but it is more complex is we have to consider view
angle and position.

Yes, I searched a top view of tux on hte web with no sucesss.
Does somebody has tux in a 3D and can provide us screenshots in top 4
position loooking north, south, east, west?

OK.

So that's a revival.

I agree with your wife. Perhaps, we should see tux in the 3D mode.
For the transparency, it works only in the bugged antialiased canvas
(gcompris -a) or you must replace the green wall by a door in png with
transparency.

Have you tried gcompris -a and putting glasses on tux in the drawing
board ;)
