Blockheads have been spotted inside the Blender computer modeling program. They are not models ported from the game Blockland to be modified, but actual Blockheads in the flesh, jets probably included.
It appears the user of the Blender session the Blockheads are trapped inside is using the program as we speak, paying no attention to the living beings jumping around their shapes.
Video footage of the incident, possibly from the POV of one of the victims, is available on Youtube.
We have yet to find a way to breach into the Blender session to interview the victims about the incident, as the footage and pictures do not provide any clues on that matter.
