Does your iPhone need to be jailbroken in order to put apps like this on it?

[cheesy9]

Yes (but not "unlocked")

chipmunk kicks phun's ass as it is open-source :)

oh, ok, thank you. this is really really cool, by the way. running it from through an ssh seems to work better for me. if i run it a few times without restarting the terminal on my ipod it can sometimes freeze though. strange. nice demo anyway. thanks

phun is a software, and API...

Chipmunk != Phun

why is the background twitching ..

[mohrtyahoo]

The screen flicker is from recording the iphone with a hand-held camera, and the frequency rates are not in sync. The iphone isn't actually flickering. The same thing can happen when you record a video monitor or tv with a camera.

[cheesy9]

The flicker is due to the demos writing directly to the screen buffer (I think). Obviously it's not the best solution, but it's just a demo :)

To end the demo, do control-C in the terminal. That terminates the program. If it's running in the background (i.e. started with "&" at the end of the command or you backgrounded it with the "bg" command) you need to find the pid (process ID) using "ps aux" then "kill #" where # is the pid.

i dont know anything about this stuff, im afraid, so sorry if the answer to this is obvious, but how do i end the demo?

[ciaran2580]

actually, i take that back.. just had to change file permissions to 755. sorry.

whats with the screen flicker though?

[ciaran2580]

have the chipmunk_demos file on my ipod, im just not sure how to run it from terminal.

any help would be appreciated...the video looks cool anyway :)
