Hammershus Castle

Hammershus is Northern Europe's largest medieval fortification, situated 74 meters (243 ft) above sea level on Hammeren, the northern tip of the Danish island of Bornholm in the Baltic Sea.

Erected in the 13th century, it was long believed that the castle was built as a private residence for the archbishop of Lund. However, new evidence found at the ruins of the castle suggests it was constructed in the beginning of the century as a royal residence for Valdemar II of Denmark and a base for the Danish crusades.

Street View Drives

I've been playing around a bit more with creating animations from Static Google Maps Street View images.

Check out Street View Drives. Once the page loads just click on any of the thumbnail images. This is the very bare bones of something I might develop further.

Then again I might get bored with it and move onto something else :)

Street View Animation

I got a little bored working on Street View Slide. As a bit of a diversion I started working on this fun animation of Street View images.

The animation captures the still images of Street Views (there is a secret Street View Still Images API) and then animates through them. The Street View Still Images API creates image tiles from the Street View panoramas. This means that if you know what you are doing you can break down the one large panoramic image into different sized images. If you then link to different parts of the larger panorama you can kind of give the illusion of turning around.

It's all a little hard to explain - just go play with the animation and work it out for yourself.

BTW - the speed buttons don't work in Internet Explorer - so if you want speed use FireFox or Chrome. The nice fade between images doesn't work in FireFox or Chrome - so if you want pretty use Internet Explorer.

Omega Centauri

I've added Hubblecast 15 to the Star Movie Map. The Hubble Telescope shows that the stars are bunching up near the centre of Omega Centauri, as seen in the gradual increase in starlight near the centre. This could be because of the presence of a black hole.

Measuring the speed of the stars swirling near the cluster's centre it was found that the stars closer to the core are moving faster than the stars farther away. The measurement implies that some unseen matter at the core has gravitational interactions with stars near it. This could be evidence of an intermediate-mass black hole.
