Read full description

Flocking is an easy to use app for early learners or special access situations. Touch and move around the screen slowly, and the fish will follow. You can also use a mouse/pointer device to lead the fish. In fact there are 8 different types of digital creatures and objects that will "flock" around your lead and follow you around until you had enough. You can change backgrounds and also change the trail that a digital creature can leave behind it. Flocking main screen can be controlled by an external keyboard. Characters 1,2,3,4, Space, Enter change the creature settings, and 5 removes the buttons from the screen. +/- change the background. Flocking can also be controlled by using an XBox controller or the Microsoft Adaptive Controller with any suitable switch inputs. The XBox thumb controller/joystick and D-Pad will move a virtual pointer around, and the controller buttons will change the effects and colors. There is a live demo on our website.
