A passerby who heard the screams of boys playing behind the Intercontinental Hotel rushed down a dock to rescue their playmate, who had fallen into the frigid waters of Fort Point Channel this afternoon.

Tez Garcia, who was nearby taking pictures of the frozen harbor at the time, forwarded photos of the dramatic rescue, which happened around 3:30 p.m.

The kids, who had been playing by themselves on sleds on a mound of snow that ended right at the water a few feet away from the water-taxi dock, start looking for the missing boy - and screaming for help:

With some help from friends, designer Don Eyles today launched Fort Point Channel's latest floating artwork: A pyramid made of plastic blocks painted to look like the paving stones that used to line Boston streets.

Eyles and a small boatload of folks then pulled the pyramid into the middle of the channel, about midway down the postal annex, and moored it in place.

UPDATE, 1:15 p.m.: After an extensive search of the surface and under bridges, firefighters didn't find anything.
