Ideas para desarrollar en j2me

Un amorometro, o sexymetro o algo asi, que con algo aleatorio determine cuanto amor hay cerca.

Un alcoholimetro para broma, es solo como una animacion y ya. podria ser un indicador estilo el de la gazolina y la flecha va subiendo poco a poco con algun sonido chusco y cuando ya rebasa el limite, se desmaya la pobre flechita.

Pininos en J2ME

Les cuento que estoy haciendo mis pininos en J2ME, Estoy usando NetBeans, y el WTK de Java en Linux Ubuntu, me gusta ubuntu por que esta basado en Debian y es sencillo de configurar.

Ya estoy probando mis midlets en un celular muy basico, con midp 2.0 los subo con un pequeño adaptador bluetooth usb, la instalacion es 100% plug and play para ubuntu.

El siguiente es un demo que hise:


import javax.microedition.lcdui.Canvas;
import javax.microedition.lcdui.Command;
import javax.microedition.lcdui.CommandListener;
import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Displayable;

// Start with lines
// La siguiente llama de inmediato a una de las opcione
//display.setCurrent(canvases[0]);
}
}
