Oh there are some more beauties here. Thanks Jack. What a find.
I think I'll have a go at piecing a couple of them; but then I think I
might set about a project of several of them - done with English Paper
Piecing. I know there's no challenge then; but I have some lovely ombre
fabric that would look gorgeous with these.
Would that be OK with you Jack?
I wouldn't be making them into a book!!!!
Tomorrow I will make a point of checking out Kali tiling.

I see it as a bunch of four-pointed stars with lozenges filling in the
spaces between them. But those lattice patterns can always be seen
in lots of different ways. Have a few more - all of them made out of
simple block shapes but not lined up in obvious ways, with no seams
running right across:

Some of the patterns you can get look like they might be useful as
qulting patterns rather than for patching:

Of course, go for it. Each one only took me a couple of minutes
of mousing. Our version of the Kali2Squares.gif pattern should
be done shortly and I'll post a photo (it's pieced, not bordered
yet). I deliberately designed it to make the underlying structure
almost impossible to work out at first sight. There obviously *is*
a structure, but somebody used to normal block settings wouldn't
immediately see the trick.

BTW, I got the idea for that quilt from a book - Grunbaum and
Shepherd, "Tilings and Patterns". All kinds of wonderful stuff
in it, and you don't need to read mathematics to see a lot of
what's going on. Probably very expensive now (it wasn't exactly
cheap when I bought it) - buying an old Mac just to run Kali
would almost certainly be cheaper.

Great! Thanks Jack. It will take a while; but it will be fun. I love
it when the construction is hidden.

The Kali4Star would actually be very possible -it's just square units
and rectangle units.

While looking for something else entirely, I came across the "Kali"
tiling pattern generator for Classic MacOS. It creates patterns
based on the 17 different plane symmetry groups. Within about five
minutes of initial tinkering with it I came up with this:
http://www.campin.me.uk/Pix/KaliHex.gif
which looks like it ought to have potential as a quilt design,
albeit not that easy to machine-piece.

Ooh! that's beautiful Jack. I'd love to have a go at it.
May I try?


Show us a picture when you're done?

We're just finishing off a version of this, which I described a while ago.
Not as straightforward as it looks:

http://www.campin.me.uk/Pix/Kali2Squares.gif

This looks doable if a bit weird:

http://www.campin.me.uk/Pix/KaliParallelograms.gif

But you can easily generate designs that look neat but would be insanely
difficult to put together:

They are appealing aren't they.

I have always thought of snowballs as melons- a melon patch block? Don't
really recall where I got that name. So we saw the same thing. I had to
look hard to see the kites and diamonds, but then found them. Yep, it's
cool how different things jump out at us!

First of all I saw it as a star with kite shapes in between each pair of
points and diamonds at the sides!
Then I could see a snowballed square with pieced rectangles set along the
sides sewn with a partial seam.
I can't see a melon at all g

Wah! I can't make myself see it any other way. The melons just keep
jumping out at me. Pat, can you explain what you see? Please? Having
studied your book I'm curious how your clever mathematically inclined mind
sees it. ;-)

LOL, I'm with you Patti. Can't see a melon at all (but then, to me,
melons are curved, not straight lines.G)
This one really doesn't seem to be all that difficult to piece, just
time consuming, depending on the size you make.

The hex example also looks very do-able. G

Friendship Ring is very similar to Jack's Chain. VBG The major
difference is substituting nine-patch blocks for squares of fabric.
G This would be an interesting pattern to vary with different small
blocks in the squares. hmmmmmmmmmm... wonder if there is a way to
show some "transparency" here?? Something to play with. G

have fun,
Pati, in Phx

Just did a fast google search on "Kali tiling" and got a site with a
downloadable program for them. Available for both Mac and Windows. G
And in several languages. Neat, and I see some more time sink here.

But not, as far as I can tell, for MacOS X. Did you find one for that?
