Reconnecting… Screensaver
The Reconnecting screensaver shows a convincing fake video-call "reconnecting" screen with a frozen frame and a spinning connection indicator. It is free, runs in your browser, and ESC exits.

How the Reconnecting… screensaver works
The saver renders a familiar video-call interface frozen mid-frame, with a "Reconnecting…" banner and spinner overlaid.
The frozen look and spinner cycle convincingly, exactly like a real dropped call.
No camera, microphone, or real call is ever involved — it is a purely visual screensaver.
Press any key or move the mouse to exit, like any other screensaver.
Why real video calls freeze
Anyone who has used video calling knows the sight: a face locked mid-expression, a spinner, and a faint sense of panic. The freeze has real technical roots. Calls typically send media as many small packets over UDP, which has no built-in retransmission or congestion control, so the software has to cope with packets that arrive late, out of order or not at all.
Video compression makes this fragile. A keyframe, or I-frame, is a complete picture that can be decoded on its own, while P-frames store only the changes from the previous picture. If a packet of a reference frame is lost, the frames that depend on it are affected too. The receiver can request a fresh keyframe when decoding has gone wrong. Browsers today tend to freeze the picture until a keyframe arrives, because carrying on decoding used to leave smeared artifacts.
A jitter buffer, a small queue on the receiver, holds incoming media briefly, reorders it and releases it at a steady pace. A larger buffer is smoother but adds delay. Congestion control also adjusts how much data the sender transmits when loss appears. This screensaver only imitates the look of a stalled call; it has no connection to your network, camera or any call software.
A worked example
Left running during a break, it reads exactly like your call actually dropped — a favorite lighthearted desk prank for remote workers.

Frequently asked questions
- Does this use my camera or mic?
- No — it never accesses your camera or microphone. It is a static visual effect.
- Is this a real dropped call?
- No — it is a purely cosmetic screensaver effect.
- Is a key needed?
- No — it runs entirely locally.
- Is it free?
- Yes — free, no download, in your browser.
- What is a keyframe?
- A complete video frame that can be decoded without any earlier frame. Other frames store only changes from the previous picture, so a keyframe is the recovery point after errors.
- Why does the picture freeze instead of showing garbled video?
- If packets of a reference frame are lost, later frames cannot be rebuilt correctly. Current browsers hold the last picture until a new keyframe arrives, because decoding on used to leave smeared artifacts.
- What does a jitter buffer do?
- It is a small queue on the receiving side that holds media briefly, puts packets back in order and releases them at a steady pace. A bigger buffer gives smoother playback but more delay.
