hope you enjoy it ;)

2. modified by poserpro, inspired  by Amnon Owed
3. I made this to combine Augmented Reality with OOP
4. print hiro marker image and use the webcam to shoot
5. then you will see the colorful rotating cube atop the hiro marker
6. the script is not perfect, but it fits my purpose for the testing though.
7. feel free to use and spread, just don'the abuse it ;P
8. **marker image can be downloaded from this link
