“I've never had so much fun with a program before in my life. This thing can do it all! You must be a supergenius or an alien or something. That's the only thing I can come up with. I haven't slept much lately creating universes. I've dreamed of a gravity simulator like this..and here it I dreamed it into existence.” ―Email from an enthusiastic fan

Language: C++ (3,085 lines of code)
Summary: DrC-- is a compiler that takes as input a source code file in C-- (a proprietary language for which the language specification is included below) and generates as output an optimized MIPS assembler code file. DrC-- implements a lexical analyzer, a parser, an abstract syntax tree creator, an error checker, a code generator, and four optimizations: dead code elimination, procedure call optimization, constant folding, and jump chaining. The optimized code runs with up to 13.3% fewer instructions. DrC-- earned a grade of A.

Pipe Scream
Affiliation: DigiPen Institute of Technology (semester project)
History: 12/08/2002 to 12/12/2002 (completed)
Language: C++ (3,960 lines of code)
Summary: For reasons unbeknowngst to the ill-fated water balloon, one day it wakes up to find itself falling down a dangerous tunnel. Our protagonist does not know how long it will have to endure this ordeal, but it is determined to make it to the bottom in one piece. (Sadly, there is no bottom.) The Pipe Scream universe is an infinite, randomly-generated pipe dominated by hazards intent on popping unsuspecting water balloons. The project was created in five days with CodeWarrior, OpenGL, Adobe Photoshop, and lots of Mountain Dew.

Summary: NTris is a variation of Tetris in which the number of blocks per piece is variable (N). As with the original Tetris, the goal is to create unbroken horizontal lines from one side of the board to the other. Because this grows exponentially harder as N increases, a wrap-around mode is implemented to help ease the burden. Other changeable attributes include the board size, the scoring, and the rate at which pieces fall. NTris was created in five separate days in February and March of 2004. It makes use of the window system developed for Overworld GDE (see above).

Language: C (10,523 lines of code)
Summary: Gravitator, the predecessor to Gravitator 2, is an interactive 2D gravity and elastic collision simulator for the Mac OS originally developed as an extra credit project for physics class. Each object has an editable mass, radius, and color. Features include the ability to edit and throw bodies during animation, a crayon mode whereby moving objects leave trails, a multiple-body edit window to make systematic changes on objects, a gravity map generator to show the acceleration due to gravity at each pixel, and 23 example systems. Gravitator was released as shareware and awarded 5/5 cows by Tucows. Gravitator was also the national winning entry in the programming category of the 2000 Young Inventors and Creators Competition.

Super Circuit Layout
Affiliation: University of Georgia (Human-Computer Interaction project)
Teammate: Richard Lanard
History: 3/2004 to 4/2004 (completed)
Language: Java (2,720 lines of code, personal contribution)
Summary: Super Circuit Layout is a Java-based circuit layout editor developed at the request of Dr. Jeffrey Smith for use in his Computer Architecture class. Users build cells out of inputs, outputs, gates, edges, and sub-cells using a simple editor similar to a drawing program. It features a development environment capable of handling multiple open windows containing possibly interdependent cells. (If edits are made to a particular cell, any other cell that contains the first cell as a sub-cell will reflect those changes. This includes the repositioning, adding, and deleting of inputs and outputs.) The application was developed in Java to allow Dr. Smith to easily expand it into a full circuit simulator. Super Circuit Layout earned a grade of A.

Summary: Pointdexter is an OpenGL-based, general-purpose 3D level editor for the Mac OS. Editing takes place from a first-person perspective. To simplify editing and improve viewing framerates, the drawing of certain rooms and areas can be deactivated. Dragging a box on the screen with the mouse will select all points whose projection lies within the box. Pointdexter includes detailed texturing tools, such as the ability to wrap repeating textures around meshes and the ability to enter the texture coordinates at a given point directly. Pointdexter also features coloring, lighting, and fog tools and the ability to save and load levels from file.

Nine Men's Morris
Affiliation: University of Georgia (graduate project)
Teammates: Philip Brooks, Astrid Glende
History: 11/2003 to 12/2003 (completed)
Language: C++ (2,191 lines of code, personal contribution)
Summary: This project examined the effectiveness of two evolved playing strategies for the game of Nine Men's Morris. The first strategy was represented by an array of linear expression coefficients that was evolved using evolutionary strategies. The second strategy was represented by a neural net whose weights were evolved in a similar manner. In both cases, strategies evolved by having strategy candidates compete in Nine Men's Morris against other strategy candidates. After the two strategies had evolved for many generations, their effectiveness against human players and against each other was evaluated. For a description of the game of Nine Men's Morris, as well as more information about the project, refer to the paper below. This project earned a grade of A.

Summary: Anagrammarian simply takes one or more phrases and generates anagrams for each phrase. An anagram of a phrase will contain the same number of instances of each letter from the original phrase. For example, “Reed's Portfolio” yields the anagram “Fool is Reported”. And perhaps not surprisingly, “Game Industry” yields the anagram “Untidy Gamers”.
