Create a square t-shirt graphic design with the following concept:

Title: Neon Eyeball Cactus in Space Helmet
Slogan: Staring into the Void, One Prickle at a Time
Visual style: line art with retro-futuristic neon glow
Mood: quirky and strange
Core concept prompt: A centered line art drawing of a single tall cactus with one large human eyeball flower on top, wearing a retro-futuristic space helmet. Neon yellow and electric blue glow outlines emphasize the cactus spines and helmet edges, all on a solid black background. The style is clean bold line art with a subtle halo glow effect around the eyeball. The composition is symmetrical and balanced with large readable retro-futuristic block lettering below reading 'Staring into the Void, One Prickle at a Time'.

Hard constraints:
- Keep composition centered and shirt-print friendly.
- Use high-contrast, clear forms suitable for print.
- Any text must be large and easily readable.
- Exclude all forbidden elements: real brand logos, celebrities, political slogans, tiny unreadable text, multiple eyes on mascot
- Do not include real brand names/logos, celebrity likenesses, copyrighted characters, political campaign slogans, hateful content, or explicit content.

Output a clean standalone design graphic, no mockup, no watermark, no background scene.
