In one corner, students pounded a vortex machine, sending rings of air catapulting to the ceiling. Across the room, teenagers struck poses in front of an advanced camera to create blueprints for tiny 3-D prints of themselves.

The Digital Harbor Foundation opened the doors of its technological playground to visitors last week during its 2nd Anniversary Showcase. Enthusiastic students, working to become Baltimore's next generation of tech professionals and entrepreneurs, greeted more than 200 attendees.

The event celebrated the work of students who attend after-school and summer programs at the foundation. Participants experiment with Web development, digital design, electronics and a variety of other hands-on technology activities. During 2014, the foundation served 500 children. In 2015, Executive Director Andrew Coy anticipates serving 2,500 children throughout Baltimore.

The foundation also launched a new national program during the showcase.
