Very nice and fluid, also great to be able to instantly buy the pattern in wrapping paper.

The only things I would recommend are:

- The help screen in the beginning, doesn't look like a modal. It took me ages to actually figure out there was an "x" button in the top-right. Maybe add a darken behind the help popup, to show that it can be exited.

- "Show Grid-lines" should be a first class option. I couldn't easily find out how to show grid-lines and without you're clicking in the dark to find where the pattern begins and ends.

These are just some small UX improvements, overall it's an impressive tool and I wish you all the best!

Also, the way the trash can icon works is way non standard. I applaud the attempt of getting rid of a standard confirmation modal, but when introducing novel UI like this you need to be more explicit.

Suggestion: - make the prompt appear inside the trash button and not outside it. That should be enough to make it more obvious. If not enough, then add a small text to it.

like this maybe:

[(Trash)Reset?]

Hello nice work but I'm afraid there is a critical bug when varying the grid size. I'm not sure you can output a tile image when using simultaneously two various grid sizes, as the periodic tiled image then should be of size greatest common multiplier of the grids size.

What you see is not what you get. https://eschersket.ch/s/52e60da7c86c26cecc6b59bb7f9de9ad

Try to see the tiled image or exported to zazzle, and lines are no longer continuous :( (By the way I also just notice sharing a zazzle url like : https://www.zazzle.com/eschersketch_wrapping_paper-256519193... is problematic because it is very tempting for the user to do so, but everyone is sharing the same link, and what is displayed have some caching issues), (Zazzle also gives a warning when the image is too big, Zazzle is also really expensive 33€ for 76cm x 1.80m)

If you can sort the above issues, you can probably easily add some fractals symmetries :)

Great software but after clicking buy and seeing that the Zazzle want to charge £37 for a roll of custom wrapping paper? haha. the economics deem this ridiculous!! You can buy great wrapping paper at a craft store for £3 a roll...

Hey - author here, that price does seem high - I don't remember it being that much... the only reason I linked to Zazzle at all was that they were the only printer at the time offering a simple API for single-button forwarding of image data. I'm sure there are cheaper services out there, which is why you can download the 'tile' image that should work with any decent printing service, or SVG for more customization, etc.

This is lovely, many thanks for sharing. I am having a lot of fun with this & will most likely use this for some art related things in the future. I'd love to be able to export these & have the same view I have via the browser. Seems that exporting picture will give me some extra space on the right with different gray space etc. Still love it, many thanks.

Watched most of the demo with my permanent roommate (an architect) before dinner and we both found it interesting. Good work.

This is awesome. Better execution than most web based tools I've seen to do similar. I'm fascinated by Escher's migrating tessellations of recognizable figures[0]. It would be nice to fork this and be able to draw a pair (or more) of figures then use a gradient to base a blending mask to sum them.

Reproducing one of Escher's works, even approximately, would likely make a killer demo for this.

This is really nice, good work!

I once made a similar thing, but it was more of a creative-play-thing for children (so no way to create tiled graphics, but hopefully easy to use and fun to play with). It is at: http://kaleidopaint.com/

Does anyone have any recommendations for a better, more economically reasonable printing service than Zazzle? The sheer cost of it is prohibitively expensive, and makes it tough to imagine small businesses or artists being able to afford using their service.
Re:Show HN: Eschersket.ch – a symmetry drawing app to design... by mkl on Friday December 27, 2019 @04:16AM (#21890130)
This looks neat! Two improvements I'd suggest are icons for the symmetry choices rather than (or as well as) technical names, and pressure sensitivity via Pointer Events.

A friend of mine has made https://patternjs.com/ but Eschersketch one is way more interactive!

Looks great! A fair bit more functionality than similar apps. I'd love to see an option to use orbifold notation as well as crystalographic.

Like in a kaleidoscope, almost anything looks much better with symmetry. Doodling on industrial scale. Great job!
Re:Show HN: Eschersket.ch – a symmetry drawing app to design... by lainga on Thursday December 26, 2019 @08:14PM (#21888283)
If I press "Grid Adjust", I think it stops the preset grid choices from applying afterward
