Catching and Collecting Forest is a free Android app developed by teamLab Inc. that is designed to be used in the teamLab Forest exhibition located in Jigyohama, Fukuoka, Japan. The app allows visitors to interact with the exhibition in a unique way, making the experience more engaging and immersive.

The app features a game where users can catch animals on the exhibition walls by using the app's camera and throwing light arrows at them or setting light nets around their feet. Once caught, the animals disappear from the exhibition space and enter the app's collection book. Users can study the animals they have caught and create their own personal collection. The app also allows users to release the animals back into the exhibition by swiping them away.

Overall, Catching and Collecting Forest is a fun and interactive way to experience the teamLab Forest exhibition. It adds an extra layer of engagement to the already impressive artwork and is a must-try for anyone visiting the exhibition.
