This is my entry for Snap X Lenslist's Spring Into Action Lensathon. It is a portal effect where the user enters an amusement park through a door. 

The lens uses Lens Studio's latest Friends component which lets the user hangout with their friends inside the park. It also uses physics for the ferris wheel and raycasting for a target shooting game in the back.
