They're the ASCII blocks in BYOB. 
I think they can be quite useful. :3

Unicode

I thought they were called (ascii code of []) and (ascii [] as letter)...

But they say unicode?

I'm talking about BYOB, you're talking about Snap!. That's the confusion.

Ahhh 

You're right that Snap 4 is a more or less complete rewrite of BYOB 3 up from the bare metal in another implementation language and in another environment. However, there is no question that the design of Snap is influenced and inspired by Scratch, and many, many underlying ideas are taken almost directly from the Squeak implementation of Scratch 1.4, including the Morphic GUI framework (which is actually influenced and inspired by Squeak and SELF). We're going out of our way to make Snap look and feel a lot like BYOB 3 and Scratch 1.4 so the transition to the new browser based Snap will be really easy for BYOB's existing users.

Incidentally I just happened to ask Mitch Resnick about this, and he suggested that we put the following text into the Snap! About Dialog:

"The design of Snap is influenced and inspired by Scratch, from the Lifelong Kindergarten group at the MIT Media Lab (http://scratch.mit.edu)"

I'm very happy with this understanding and from tonight on this is what we will say about the relationship between Snap! and Scratch.

(actually, I think the relationship is much stronger, and I personally believe that Snap! is based on Scratch, and not just "inspired" by it, but I'm fine with whatever is the preferred way to give credit to the über-awesome design genius of Mitch, John and the MIT Scratch Team)

Snap Glitch —

The sprites (turtles) can be moved off the stage (directly with the mouse, I haven't tried it with programming them) and into the scripting area.

yeah, well, we don't have the "slide back to former situation" feature implemented yet...

Bug report:

If I create a custom block and set the category to the operator category, when I press ok and click on that category nothing shows up.

This only happened on firefox 10.0.2 on Mac OSX Snow Leopard.

This did not happen on my windows machine running the same browser.

you need to type in a name for the block

@Jens
I've written a dozen of small "Snap! initiation games" using the Chrome browser. No problem for Saving/Loading these applications written on a PC in the city A . From there I had to move to a city B where I work with an other PC. Not surprisingly I don't find my previously saved application on this second PC.Nevertheless I'm curious to know where have been saved my applications ? Into a server on into some hidden Chrome file ?

Hi Xavier,

your projects are saved locally on your hard disk in what is called your browser's "local storage". This is basically the same as a big "cookie". This isn't nice but at least it - kinda - works for now. We're also discussing ways to support real cloud storage. Stay tuned!

Thank you, Jens and Snap!ers for your help.
I'm rather oldish, still Windows XP, using for Snap! mainly Chrome and sometimes Firefox.
In both cases I've no found any file correponding to a Snap! project (it would be too simple for Microsoft !)
The "joefarebrother" method does not work either, neither with Chrome, nor Firefox.
Anyhow , Chrome has a "save page" feature and I have saved 5 of my projects into *.htm file format which gather all Project codification. But I can't reload it into Chrome.
Well, I know that this issue will be fixed in due time, it was just for the sake of understanding the situation.

The main thing to understand here is that "local storage" is a technical term in HTML5 for a sort of browser-private file system that's encrypted on your disk, and the project names you use don't correspond to names of ordinary Windows files.

They use this complicated system so that if a web page downloads a virus or other malware, the encryption will turn it into gibberish that can't harm your system, and you can't accidentally copy it to someplace else where it might make trouble.  This is why people won't be afraid to run Snap! in their browser and save their own projects.

The official correct solution is cloud storage.  We'll get there.  But meanwhile, as a temporary workaround, when you save a project, the URL at the top of your browser window is changed to a really really long one that encodes your entire project!  So there really is no .html file that contains your project; the URL is still snap.berkeley.edu/snapsource/nasciturus.html but now after the ".html" comes a bazillion characters unique to your project.  You should be able to copy this (click in the URL bar and control-A, control-C) and paste it wherever you want: a text editor, another browser, whatever.
