thanks for the info, I will take a deeper look into the code for more details. By flat I assume you mean squared , so that it does not need anti-aliasing so much.��

Anti-aliasing is definitely something that interests me deeply but so far I have been happy with Athens in this department hence why I asked about the usefulness of Balloon.��

So that means Morphic supports anti-aliasing through Ballon which is indeed very good news for me.��

Athens came after Balloon.
Morphics rendering is based on Balloon.
Balloon engine is used for special rendering (see asBalloonCanvas), for example
complex borders, it uses a plugin (B2DPlugin), has (has better) antialiasing.

I think balloon based rendering is much more importent for squeak than pharo.
(Pharo looks more flat). Take a look at older squeak releases (screenshots)
to get a feel of it).

Can someone explain to me the importance of Pharo's Balloon engine ? What it offers that Athens and Morphic dont already have ? In which scenarios its worth using ? Where I can find documentation about it ?��
