What is leap t03?

As an AI language model, I don't have any specific knowledge about a product named "leap t03". However, "Leap" could be referring to the Leap Motion, a hand-tracking technology that can be used to control computers with hand gestures. If that is what you are referring to, the Leap Motion Controller attaches to your computer and allows you to interact with programs through hand gestures and other natural movements. It has been used for virtual and augmented reality applications, gaming, and in prosthetic limbs.
