Beautiful video-mapping show projected on Prague's 600-year-old medieval Astronomical Clock

This video is a digital 3D projection that is being done on the face of the Prague Astronomical clock to celebrate the 600th anniversary of the clock. The clock shows not only the time, but the phase of the moon, how much time until sunset or sunrise, what zodiac sign you are in, so in the video you can watch each of those aspects being added to the clock as it is being “built.” It’s really beautiful.

Sound Absorbing Plaster?

Have any of you seen this interesting new construction technology?

BASWpahon is a new wall finishing system that provides “Seamless Acoustical Finishes”. This is an alternative to acoustical plaster which is typically specified and installed to control reverberant spaces.

How does BASWAphon work?

BASWAphon “filters out” echoes and reflected sound, making conversation clearer even in harsh situations.

The BASWAphon Seamless Sound Absorbing Plaster System is used to reduce reverberation time making voice, music and other sound much more intelligible. Its design is based on a fine porous surface that appears to be solid, applied onto a mineral wool panel.

High frequency sound energy passes through the pores, into the mineral wool, and is converted into heat energy. Low frequency sound energy vibrates the porous surface diaphragmatically, transforming the sound energy into heat energy.

Fremont Street Experience - Queen Tribute

Nice use of the Fremont Street display. The LED display "canopy", runs along the Fremont Street Experience promenade from Main Street to Fourth Street. Holding the canopy aloft are 16 columns, each weighing 26,000 pounds and can hold up 400,000 pounds, and 43,000 struts.

A section comprising one fiftieth of the total canopy equals the size of the world’s current largest electric sign. More than 12 million LED lamps illuminate the overhead canopy. The new LED upgrade was designed and engineered by LG Electronics, who is also the primary corporate sponsor of the canopy. Within the canopy itself are 220 speakers powered by 550,000 watts of amplification.

The Foundations of the Stereoscopic Cinema, A Study In Depth” by Lenny Lipton

I just found out that the book “The Foundations of the Stereoscopic Cinema, A Study In Depth” by Lenny Lipton is available as a PDF for free download for personal use only. This book has been out of print for years. It is a great source of information on all things related to the way we perceive 3D. For those of you who want a lot of information on plano-stereoscopic systems, their history and the science behind them, it’s a must (but very technical) read.
