With embedded systems gaining high resolution  
displays and powerful CPUs, the desire for     
sophisticated graphical user interfaces can be 
realized in even the smallest of systems.      
While the CPU power available for a given      
power budget has increased dramatically, these 
tiny systems remain severely memory            
constrained. This unique environment presents  
interesting challenges in graphical system     
design and implementation. To explore this     
particular space, a new window system, Twin,   
has been developed. Using ideas from modern    
window systems in larger environments, Twin    
offers overlapping translucent windows,        
anti-aliased graphics and scalable fonts in a  
total memory budget of 100 kilobytes.
