If, like many people, you find Mondays just too much to cope with, you might want to avoid today’s app. It’s not the sort of thing that’s going to make your Monday feel any better, and in some cases it will just fry your brain until next Monday. Which would be a shame, because you’d miss out on a whole weekend.
Be forewarned, then: The Fourth Dimension is an app which will mess with your head. Deliberately. Even though the aim is education and expansion of knowledge, it will still mess with your head. You will emerge from the experience only fractionally the wiser, and quite a lot more confused than you were at the beginning. Don’t worry, this is perfectly normal.
The Fling controller from TenOne Design (soon to be reviewed) is a great way to add a physical to your iPhone or iPad, just by suction-cupping it onto the screen. This means that it works with any game on your iOS device that uses an on-screen “joystick.”
The downside is that it moves at the worst moments: I have wiped out in more than one GTA car chase this way. But designers at the Keio University in Japan have come up with another idea. A joystick which uses the iPhone’s camera as a controller.
Ever wonder why ƒ-stops have the numbers they do, or what those numbers mean? Watch this great video to find out
Ever wonder how those funky aperture numbers ended up on your lens barrel? Or who chose those odd ƒ-numbers that run in the seemingly arbitrary 1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32 sequence? And why does the biggest number refer to the smallest lens-hole?
Now, video sketching supremo Dylan Bennett is back to explain ƒ-stops to you. Grab a beverage, sit back and enjoy 15 minutes of easy-to-follow explanation. With drawings!
If you’re frustrated that your app was rejected from the App Store, you are in good company.
Scott Virkler, senior vice president of eProducts at global science and medical publishing behemoth Elsevier, had a few choice words about Apple’s approval process – and getting rejected by it.
Virkler, speaking in San Francisco at Appnation Enterprise, said his company had three apps rejected by Apple just last week, “because they don’t get our business.”
Solar Walk is an excellent educational app about space and everything in it. With Earth as your home base, you wander the Solar System, cruising the planets and moons and making discoveries along the way.
NASA has released version 2 of its popular Space Images app for iPad, and it’s lovely.
It’s packed full of gorgeous images from pretty much every aspect of the space agency’s work. Each one comes with a brief explanation, and you can fave or rate the ones you like.
Even better, you can save images to your iPad and use them as wallpapers. And all of this is free. If you have an iPad and you have kids, or even if you don’t have kids, this is well worth downloading.
This week’s photographic obsession is Dominik Seibold’s Hough Transform Camera, which I can explain in two different ways: the simple way, and the science way.
