[Squeakland] [Q] add new sound, Kedama in OLPC image

Hello,

I have a few questions about the OLPC version of eToy, which I downloaded from http://etoys.laptop.org/src/etoys-image-and-pr.zip .

First, it looks like the current eToy image that can be downloaded from squekland web site cannot open OLPC-eToy projects. I assume that the Squeakland download version will be replaced with the OLPC version. I guess that my quetion is if I use the OLPC version now, will my eToy project can be opened in the future Squeakland download version?

Second, is there a way to import an mp3 file and use it in a sketch? In other words, I want to add a new sound in the "sound" category of the sketch viewer. Is this possible?

Third, the Object catablog of the OLPC version does not include Kedama. Does this mean that Kedama is not supported in the OLPC version? I guess not, because I saw Kedama examples, e.g., ParticlesDyeInWater.009.pr, in the ExampleEtoy folder. But, I could not figure out how to do a Kedama project in the OLPC version. Can anyone explain how to do the Kedana project in the OLPC version?

Thanks in advance.
