This is a magic pen... To use: Hold the space bar and the pen will follow your mouse. The up and down arrows lift the pen and use the pen. The left arrow clears all, while the right arrow stamps. "Z" changes pens, "N" or "0" erases, and "M" changes colors. "1", "2", "3", "4", "5", "6", "7", "8", and "9" change the colors to red, orange, yellow, bright green, dark green, light blue, dark blue, purple, and black. Press "B" to change background. List of colors: 1=red 2=orange 3=yellow 4=light green 5=dark green 6=light blue 7=dark blue 8=purple 9=black 0=erase N=erase M=magic
All my idea.
