Hi Guys

I was wondering if you guys have got any good software where i can create a virtualk tour of school?
i know there is
- easy pano - its bit difficult to use
- 3D Vista - expensive to purchase them
- Kolor Panotour - again expensive to purchase them too

is there any free software where i can download from sites or anyone have one to send me .

As i wanted to create a Virtual Tour of school

thanks for your help
