GDI+ Abacus

Graphical VB.Net reimagining of the primitive counting device.
Uses just a bead Class, each instance representing one of the beads on the frame, a custom EventArgs Class and a Form.
The counting frame is set as the form BackGroundImage, and the beads are drawn directly on the Form. You can drag either one or a block of beads across the frame. At the minimum allowed and the maximum allowed Left position for each bead, there's a 'snap to' feature which pulls the beads into position, and makes it possible to calculate the total easily.

Thanks for this Paul, I've been thinking how to develop a project for my daughters class and this has given me some inspiration I'll unzip it and look through the code to see how much of it I understand and can adapt.
