Chris Walsh wrote the first independent program to control the new attribute modes of the SPECTRA interface. His Snake demo displays a number of snakes moving about the screen, changing direction as they collide. A range of attribute modes are supported, with the finest resolution being the 4x2 DB mode. This results in snakes of only 2 pixels wide and yet with no attribute colour clash. Screenshots from the program are shown below:
The demo can also be run on a standard Spectrum, although only using the standard colours and colour resolution:
The program supports a range of configuration options for adjusting how the snakes move, which can result in some very hypnotic movement patterns.
