A corn maze announcing the annual Iowa - Iowa State football game just East of Ames, Iowa. The image is on its side but you should be able to see the University of Iowa’s ‘Herky the Hawk’ to the right and Iowa State University’s ‘Cy’ tornado-thing to the left. Below is the date of the game - Sept 13, 2003.

Here you can see the unmistakable ‘noses’ of a couple of Japanese Shinkansen Super Express trains, although you might know these better as ‘Bullet Trains’. Their nickname is well deserved however, as they regularly run at speeds of 300 kilometres (185 miles) per hour… and they actually plan to increase that speed to 360 km/h!

Woah, that’s a whole heap faster than Scotrail ever gets

Can anyone find one of the Doctor Yellow trains which they use for testing the tracks? They shouldn’t be that difficult to spot (being that they’re bright yellow) but there’s only ever been 5 of them, and they generally only run at night…

There’s loads of really interesting stuff about this incredible feat of engineering over at Wikipedia.

Thanks to Flo, and me

An alien monolith perhaps? Or just some rather interesting stitching? Pretty cool looking though

Thanks to Kristian.

The Fernsehturm (literally, “TV tower”) was built in 1969 and features a revolving cafe and observation deck. Aside from the obvious function of providing TV and radio signals for the city the underlying motivation for the tower was to create a powerful political symbol in East Germany that could be seen by the West.

The buildings around the tower appear to be in the shape of an aeroplane, but I couldn’t find anything saying if this was intentional or not. Also look for the tower’s large shadow extending to the North, the train station ‘Alexanderplatz’ just to the east and the orange roofed church St. Marien to the west .
