LANPaint is a simple paint application which alows you to draw and send your drawing online to other people connected to the same network.

• Choice between pencil and eraser
• Tool thickness
• Pen color
• Background color
• Clear all the content
• Undoing and redoing drawing with CTRL+Z and CTRL+Y shortcuts
• Saving to a file and opening from a file your previously saved drawing (CTRL+S and CTRL+O)

• Broadcast drawing, erasing, changing background, and clearing to other participants
• Synchronize (sending all your content to others)
• Turn off/on broadcast of your own drawing to others
• Turn off/on receive drawing from others
• Choose Network Adapter and port for interaction

Networking is just a UDP broadcasting, so it's not reliable but instead very simple to implement.
