Need a project

I was wondering if anyone had any project ideas i could use :P I'm kind of bored, and can't think of any on my own.

I've always wanted to create my own Java based forums software but that might be a bit of a big project. I'm keen on doing a small game using OpenGL with you if you like. Just as minor as minor can get really, start small.

Hehe, i found a small project to do: Tetris :D

That would be fun to do ;)

It's not much yet, but here's what i've got so far:
Main applet program

Code :

package applet;
 
import java.applet.Applet;
import java.awt.*;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import pieces.Piece;
import board.Board;
 
public class Tetris extends Applet implements Runnable, KeyListener
{
    Board board;
 
    public void init ()
    {
        board = new Board(10, 20);
        /*
         * test code: uncomment to test painting
         *
         * for (int i = 0; i < board.getHeight(); i++)
         * {
         *  for (int j = (int) (Math.random() * 5); j < board.getWidth(); j += (int) (Math.random() * 3) + 1)
         *   {
         *      board
         *               .addPiece(new Piece(new Color((float) Math.random(), (float) Math.random(), (float) Math
         *                       .random())), i, j);
         *   }
         * }
        */
 
    }

Cool, good stuff :D

I was wondering if someone would develop the graphics/gui? Right now, I pretty much have place-holder objects. Sound/Music would be nice, too.
