title: Using desktop as canvas on linux
body: <p><br>
  i was wondering if somebody could help me out. I have a plan of making clone of geek tools for linux. But i have no idea if you can somehow use linux desktop as canvas for drawing text etc. I tried to google it up but i found nothing. What i need to do is basically be able to draw text on certain parts of desktop so it would appear like they are part of wallpaper (from c++). Either that or be able to create borderless, transparent windows that can be clicked through and are always on background. If anyone could give me any pointers where to start, i will be very happy.

  Thanks for your help in advance :]</p>
