Quick summary and practical advice building on 's request and the two suggestions already posted by and .

There are three practical ways to get a non-rectangular window:

  • easiest: color-key transparency (what hinted at) — set a single background color as the form's transparency key;
  • managed-shape: set the form's Region (GraphicsPath) or call the native SetWindowRgn (what pointed to) for a true shaped window;
  • best visual quality: use a layered window with per-pixel alpha (UpdateLayeredWindow) for anti-aliased edges and semi-transparent pixels (this is what real media-player skins typically use).

Which to pick:

  • Use TransparencyKey for a quick prototype or very simple, hard-edged shapes. It is easy but fragile: anti-aliased PNG edges will get fringes, and the key color must not appear inside the art.
  • Use Form.Region (managed) or SetWindowRgn for crisp cutouts and correct hit-testing: mouse clicks outside the region are ignored. Regions are binary — no semi-transparency or smooth blended edges.
  • Use a layered window (UpdateLayeredWindow) when you need smooth edges, shadows or semi-transparency. It requires drawing your window into a bitmap and is a bit more work (you usually draw the whole window yourself).

Practical notes and gotchas:

  • Remove the border (FormBorderStyle = None) and position the image so the transparent areas match the region/key.
  • If using TransparencyKey, pick a color not present in the artwork and avoid anti-aliased borders.
  • If you go layered, be prepared to render child controls yourself (layered windows are typically composited from a single bitmap).
  • For managed code, the Form.Region property is the simplest managed API; the native SetWindowRgn and UpdateLayeredWindow are in the Win32 API if you need lower-level control (Form.TransparencyKey, , SetWindowRgn, UpdateLayeredWindow).

You could probably accomplish this, at least in a basic format, using the transparency color key for the form itself. (i.e. lime green is transparent, and having the background of the image/skin be the lime green). I'm sure there is a better method though.
