Hi,

I studied  abit javascript and Victor's pnacl examples and wrote some tryouts 
that are up on:

http://tarmo.uuu.ee/varia/failid/cs/nacl/
(work only in google chrome 31 and later, no csound installation needed)

1) name2music - this an online port of a soundgame I created for kindergarden 
children - enter your name and play with it. Originally I used arduino and two 
proximity controllers, so children could move their hands in the air and 
change the sound. Here replaced with a canvas.

http://tarmo.uuu.ee/varia/failid/cs/nacl/name2music.html


2) server-sent-messages-test: more simple, but potentially more interesting: 
This a rudimentary test for network based but synced csound music.
Here the sounds are played when server send a message (as described in server-
sent-test.php). The php sends a midi note number on every 2nd second, synced 
to the system clock of the server. So all people loading page 
http://tarmo.uuu.ee/varia/failid/cs/nacl/server-sent-test.html
should hear the same sound (almost) on the same time.

The idea is: streaming audio and doing all the buffering is heavy and slow. 
Why not to send just messages to all clients that compile and play the changes 
almost instantly (well, there is is the network latency, but this is still 
relatively small).

I don't know the html5 technologies much, I tried server sent event as it was 
relativley easy, there are also websockets that are much more powerful and 
probably the right way to go. But  I will not start learning it right now.

Still -- there is VAST potential, the nacl module is just awesome!

Thank you, if you can try it out and tell your ideas or feedback!

greetings,
tarmo


PS in the server-sent-test you get every now and then error "Serve sent event 
failed". I saw the logs on the server that a php script is allowed to run max 
30 seconds, I guess it is because of the restart of the script. There must be 
ways to solve it, but I will not do it now.

Nice ideas. Thanks for inspiring examples.
best,
Oeyvind

And don't forget all the JQuery UI stuff. There also exists a lot of plugins.
