Does anyone know of any good, easy-to-use software that can be used to make complicated tessellations? (Like a graphics editor.) I want to be able to start with a basic figure (quadrilateral, triangle, hexagon) then use a lasso/cutter tool that will allow for shifting pieces with the end result of a complicated figure that can be tessellated. I plan to make tessellations by means of reflection, rotation, etc. (Perhaps even dilation -- fractals.) I tried using MS Paint, but as figures get more complicated, you must pay attention to lining up each pixel perfectly when shifting pieces of the original figure, which can be difficult. Thus, the program should preferably have a snap-to feature of some sort to ensure the figure will tessellate. Basically, I want to be able to create intricate figures that can tessellated, a la MC Escher (Example: ( http://www.worldofescher.com/gallery/A30L.html [maybe not as complicated as that though]), and need a program that can assist me. Thanks for your help. Sorry if I have confused you.-- Proficient 05:55, 13 November 2006 (UTC)
Whenever opening a new account of whatever kind on the internet, among many different details, you are usually asked to "enter the characters you see below," and are then presented with strange looking words. I would like to know what this is. So far I've found that it prevents automated accounts being produced, but how and what is actually going on here? Gerard Khun 08:08, 13 November 2006 (UTC)
One downside is that they prevent blind and visually impaired users from registering, as well. Those users can use screen readers to navigate through the web site, if they can get past the registration process. StuRat 22:06, 13 November 2006 (UTC)
any reason why cant we burn dvd format on a cd???
My computer is about to get Windows XP, but to make it work properly, we're going to install it on a separate harddrive rather than installing it over Windows 98. What is the best way to retain my Firefox personal settings and extension information? I seem to remember a mass extension installer that worked from a txt file. Does anyone know where to find that? Any other tips? - Mgm| (talk) 20:18, 13 November 2006 (UTC)

Is there a correct way of having text within a <td></td> element (and perhaps within <p></p> elements within <td></td>) conforming to CSS 2 and XHTML 1.1/2? Since tables were supposed to be used for tabular data, browsers automatically center the data within it, meaning if you've got a big image on the same row as some text in another cell, it gets floated to the middle. Since they're supposed to act in this way, I think there is not supposed to be a way of aligning text vertically within tables (since you're supposed to use <div> and <span> for positioning non-tabular information).
Using the CSS valign: top; is not valid for text (only images), this cannot be used, dispite it having the desired effect in most browsers, and will create a markup error when the page is validated. RevenDS 20:42, 13 November 2006 (UTC)
You need the CSS property "vertical-align: top" for both the image and the table cell ☢ Ҡi∊ff⌇ ↯ 18:33, 14 November 2006 (UTC)
Left-side text | ![]() | Right-side text with a second line. |
Does anyone know of a free downloadable program (can be used offline) that can parse phrases like "265 kilometers per hour in meters per second" or just in general convert between arbitrary units? Jon513 22:10, 13 November 2006 (UTC)
% units "64 lightyears per century" "kilofurlongs per nanofortnight" * 1.1536975 / 0.86677831
$ units 2438 units, 71 prefixes, 32 nonlinear units You have: 742 millibar You want: mmHg * 556.54569 / 0.0017967977
