Touch the foggy window to wipe away condensation, draw or write on the glass, and reveal the view behind it.
Move your finger across the glass to draw shapes, write a message, or wipe away a wider patch of fog. On a computer, click and drag with your mouse. Rub the same area again to reveal more of the view.
Use the Fog returns slider to control how quickly your marks fade as condensation covers the glass again. Choose a return time from five seconds to five minutes, or select Never to keep your cleared areas during your visit.
Choose a nature background from Settings to change what appears behind the foggy window. Wipe the glass to uncover leaves, flowers, snowy branches, and other scenes, then switch backgrounds whenever you want a different view.
Select Upload photo to choose an image from your device, or Take photo to use your camera where supported. Your picture becomes the view behind the condensation. It stays in your browser for this visit and is not uploaded to a server.
Tap the reset button to cover the window with condensation and clear your drawings. Your selected background stays in place, ready for another message, a new pattern, or a fresh sweep across the glass.
Use the fullscreen button, where available, to give the foggy glass more room on your screen. Draw, wipe, and reveal the scene across a larger area, then exit fullscreen to return to the page.
