Thank you all ! I've tried to make a "Why Pharo is different" screencast, I'm pleased that it seems to work :) If you have the courage to put these comments on pharocasts itself (even to say it's crap, just tell why), I will be very grateful ! (and it shows that the community is here)

Hi. I wouldn't like to loose all this cool pieces of code. Even if they are not complete, they work as examples. It would be good to create a ss project like ExternalWebApplicationsCommunication or something like that where you post all this code, Gary's one, and I remember others from your posts or other emails....

I think that a chapter on fun scripting the web with pharo would be better than an help.

These screencasts are *priceless!!!* "Programming with live objects" rocked my world when I first started with Smalltalk - it was like a child learning how to walk by seeing someone walking. Oh, and the best part is that you can so quickly get to any part of it via rewind/fast-forward - very helpful! Done. And thanks for asking, I didn't even think of it :)
Cheers,

Ask away if you'd like more examples of
Morphic/Polymorph things...
Even for me, that was the first time I used a Block
as the model for a button! :-)

I think everybody want to have (lot) more examples ;) More seriously, on Pharocasts the GUI tab is the most clicked one by far (according to google analytics), so I suppose a lot of people want (including me) to start by doing a little graphical app. Polymorph seems cool, but aaarggghhh almost no documentation. Indeed I'm just starting to feel the logic behind it so I will try to record more screencasts on it.
And I think that's how it should be for all callbacks: it's far easier to think (for me at least) and design by giving a block to an action than a selector and a model.
Laurent (who is waiting for more examples :)

Well, with the refactoring Stef and I did at
CampSmalltalk, blocks (as an action) are now supported for buttons.
I'll have to add some helpers (or make the existing
ones agnostic) to TEasilyThemed for convenience though.
