Dragulescu uses algorithms and data culled from blogs, spam, and other computer files as his raw materials. For the MessageLabs commission, he developed images using actual malware code."For each piece of disassembled code, API calls, memory addresses, and subroutines are tracked and analyzed," Dragulescu explains on his site. "Their frequency, density, and grouping are mapped to the inputs of an algorithm that grows a virtual 3-D entity. Therefore, the patterns and rhythms found in the data drive the configuration of the artificial organism."
We talk about computer viruses as if they are biological viruses. They're not, of course, but if they were organic entities, this is how they might be expected to look under a microscope.
