Who: Bob Noble is a 8 Bit Game Music Maker of 4 years. I think he's pretty amazing and is offering free music for people who make games. 
 

How: This was a lot of work, It took me 10 hours, and I placed many pixels my self. I am such a Noob at this, but I thought doing this study would teach me about value and banding.
