Halftone is a stippling technique that simulates a gradient of various shades with a limited number of tones, in this case of two contrasting colours with a black and white shading. Although it was created as a result of the limitations of print techniques, a halftone pattern effect is trivial to reproduce using modern technology, and allows the summoning of entities with little to no side effects to the magus. At this point, the neon strip lights must be arranged pentagram-wise, and on no account must the magus step beyond their limits, no matter how the hash values produce variations in size and orientation. A radio and good batteries are a must.
