Dwees Design

What this script does it allow the user to enter their text into a box, and when they click submit, it sends the information via Ajax to a server side script that processes the information and creates an animated gif from the information. The server side script (written in PHP) then sends back the location of the image, and the client side JavaScript updates the page with the image.

It doesn't have any features really, but it should pretty easy to add some.

I'm the maintainer and creator of a filter module for Drupal where users can enter mathematical equations (using MimeTex.cgi created by John Forkosh) and create graphs which are built on the fly (using the JavaScript grapher created by Walter Zorn).

Some examples:

This plugin requires the Dimensions plugin and jQuery version 1.1.3+.

It allows you to define a gradient fill and have an element filled with a gradient. You can set the direction of the gradient (right-left or up-down) and the opacity of the gradient easily.

It uses the excellent jQuery JavaScript library developed by John Resig at http://jquery.com.

You can see some examples at http://www.unitorganizer.com/javascript/gradients/.

I'm working on a script that allows a user to enter in a logical statement in symbolic form, and then the script creates the truth table for that logic. It doesn't work perfectly yet, but it's an interesting exercise. One of my students asked me if the reason we studied logic was partially because of computers, and I agreed.

I just created a script which creates a simple factor tree for many numbers. There is a maximum limit to the size of the number where the script is completely effective, but it is very large.

This is something I wrote to make my life easier when testing the process my students have gone through to simulate a simple problem in probability. Basically, it simulates the random sampling the students have gone through, and then creates a simple histogram to show the data.

A colleague of mine at work showed me a Java applet where the user could see various sets represented using Venn diagrams, and I decided to build something similar in JavaScript. I was going to do it in Flash, but JavaScript was easier to debug (especially given that I didn't have a copy of the Flash editor available to me at the time).

So today during my lunch hour I decided to code a Spaceship shooting game. It's not complete, but so far I have the background moving and the spaceship moves as you press the right and left arrows, and the spacebar (or enter key) let's you shoot out lasers.

Not especially impressive yet, but a bit of JavaScript fun.

So I created this script that lets my students try out different transformation matrices on a vector and see the result of the transformations. From this I am hoping we can come to some conclusions as to what the transformation matrices are (at least in terms of dilation of scale etc...).

You can view the script here.

This should work in most browsers including IE (assuming you have VML support enabled).

So I've been working again on the spreadsheet I was creating before, and I've worked out some technical difficulties. The new version is also slightly nicer in appearance than the old version, although I need to get it looking the same in everyone's browser.

It's not fully featured yet, but I have yet to decide what features of a regular spreadsheet I should implement, and what features are unnecessary.
