A stylized CRT monitor displays a weekly streaming schedule for VTuber "Deuterium" using a retro command-line interface. The screen reads: Monday to Thursday: No Stream Friday: Hollow Knight Part 5 Saturday: Darkenstein 3D (the game I'm in!) The monitor sits against a blue tiled background, with the phrase "the Sentient Mattress" at the bottom.

Stylized graphic of a retro computer monitor displaying a command-line interface. The screen shows a weekly streaming schedule for a content creator named "Deuterium." The schedule lists: no streams Monday to Wednesday, "Hollow Knight Part 2" on Thursday, "New Horror Games Anthology" on Saturday, and no streams on Friday and Sunday. The background features a blue grid pattern, and the bottom of the monitor reads "the Sentient Mattress."

One of my closest friends once called me an "absolute teddy bear" and that should tell you most of what you need to know about me! #InnocenceTest #ImInnocent

A digital image designed to look like a retro computer monitor displaying a stream schedule. The monitor's screen is black with light blue text, mimicking a command-line interface. At the top, "Deuterium" is the title. Below that, "C:/>Deuterium/StreamSchedule" is displayed, followed by a daily breakdown. The schedule reads: Monday: (no game listed) Tuesday: No Stream Wednesday: No Stream Thursday: RAGE Friday: Deadzone: Rogue (thanks to Keymailer!) Saturday: Quake + Jackbox Sunday: No Stream At the bottom of the screen, "C:/>_" is shown, indicating a blinking cursor. The entire monitor graphic is set against a background of light blue squares, resembling a grid or graph paper. Below the monitor, in a stylized font, it says "the Sentient Mattress".
