Here you see four gray tiles on your left, seven gray tiles on the right.

And all the tiles match up again.

The thermal tiles fall off.

Puzzle game based on hexagonal tiles

Complete the puzzle by matching numbered tiles

And we like to draw these tiles as little squares.

Clear the screen by removing groups of colored and shaped tiles

The four blue tiles on the left are gray.

Disassemble a pile of tiles by removing matching pairs

This is literally the colored sequence of those tiles.

The seven yellow tiles on the right are also gray.

So, these tiles would make a complicated, self assembling checkerboard.

Where do you get lumpy tiles? Well, of course, you don't.

Here is a DNA origami rectangle, and here are some tiles growing from it.

Because if they put tiles on top, it's just going to crash.

All right? Whereas on the right, the two tiles look nearly the same.

We're going to turn to another technology, called algorithmic self assembly of tiles.

So if you affix some wires and switches to those tiles rather than to the staple strands, you affix them to the tiles then they'll self assemble the somewhat complicated circuits, the demultiplexer circuits, that you need to address this memory.

We've got bubbles going up there, then suds at the top with lumpy tiles.

It was work actually by Lionel Penrose, father of Roger Penrose, the tiles guy.

By early 2005, the barrier was approximately 205 km long, of which 24.1 km consisted of concrete slabs and 181 km was fence like in structure.

But if you're the leader on it, at the hardest move, you're looking at about 100 foot fall, onto some low angle slabs.

Semi finished products are steel shapes (blooms, billets or slabs) that are later rolled into finished products such as beams bars or sheet.

Here's the DNA origami, and what we can do is we can write 32 on both edges of the DNA origami, and we can now use our watering can and water with tiles, and we can start growing tiles off of that and create a square.

Notice that on the left the two tiles look nearly completely opposite one very white and one very dark.

That is your perceptual reality. The physical reality is that those two tiles are the same.

Whereas on the right, the information is consistent with those two tiles being under the same light.

Try to end up with the tiles in numerical order, with the space in the bottom right

He just lay in the hospital bed, and, kind of, stared at the polystyrene ceiling tiles for a really long time.

And we put down those little floor tiles, and then I went onto eBay and bought 150 pounds of Lego which is insane.

We have two identical tiles, on the left, one in a dark surround, one in a light surround.

Seismic standards and confined masonry, where the building acts as a whole walls and columns and roofs and slabs tied together to support each other instead of breaking off into separate members and failing.

But I get a lot of toilets, and so you just dispatch a toilet with a hammer, and then you have lumpy tiles.

And the point of this, if you didn't catch that, is that tiles are a kind of molecular program and they can output patterns.

It was started by Erik Winfree, and what it does, it has tiles that are a hundredth the size of a DNA origami.

Her crossing the fragmented tiles, faltering at the step to the street, droning, not looking at me, Can you help me?

So, what we've done is we've succeeded in making something much bigger than a DNA origami by combining DNA origami with tiles.

I'm not going to change those tiles at all, but I'm going to reveal the rest of the scene and see what happens to your perception.

You zoom in, there are just four DNA strands and they have little single stranded bits on them that can bind to other tiles, if they match.

So, you can come up with a set of tiles that when they come together, form a little binary counter rather than a checkerboard.

In the old days, when communist central planning suffocated China s economy, fixed asset investment was the regime s measure of economic progress. The more tons of steel produced, slabs of concrete poured, and gallons of crude oil pumped out of the ground the better.

This was just a proof of principle he did of tiles that interact magnetically, where you write a code, much like protein folding, that specifies their structure.

But if we use a little computation we use origami, plus some tiles that count then we can get away with using 100, 200 or 300 DNA strands.

I've kept the tiles I've kept the floors I've kept the trunking I've got in some recycled fridges I've got some recycled tills I've got some recycled trolleys.

You can see here in this time lapse video that the sun, as it moves across the surface, as well as the shade, each of the tiles moves individually.
