Reenable a bunch of old portal play stuff, like dropping grenade into portal on hog, jumping through portal w/ hog on other end, collecting crate w/ portal etc. Also add cooldown to cake/portal interaction. It may still not do what you expect, but it probably shouldn't spin in place.

#include <stdio.h>
#include "openalbridge.h"

int main (int argc, int **argv) {

    openal_init();

    openal_close();

    return 0;
}
