“BLOCK”是使用 FontVibe AI 创作的3D 立体粗体文字效果。厚重的方块大写字母带深度挤出，每个字母一种亮面糖果色，顶光让高光滚过圆润边角，彩色倒影落在地面上。

Massive chunky 3D block letters with heavyweight extruded presence — thick uniform extrusion depth of 50-60% of letter height. Front face finished in ultra-glossy lacquer, catching directional key light with natural specular reflections that graduate from bright highlight to deep saturated color — the surface quality of hard candy coating or high-gloss toy paint. Side extrusion planes in a noticeably darker shade of the same hue, creating crisp face-to-depth contrast that reads immediately as three-dimensional volume. Adjacent letters each carry a different vivid saturated color, maximizing chromatic contrast across the word — no two adjacent letters share the same hue family. Hard sharp corner edges where face meets extrusion, no beveling. Long dramatic cast shadows at consistent 45-degree angle, shadow depth approximately 40-50% of letter height. Strong directional key light from upper left. Bold, high-contrast, maximum visual impact. A gaming live stream setup — a streamer's desk with dual monitors, RGB keyboard and mouse, gaming headset on the desk, soft blue-purple ambient LED lighting behind the setup. A large LED panel / display screen on the wall behind the streaming desk. The background LED panel displays the stream branding: "BLOCK" in massive colorful 3D candy-surface block letters as the channel name / game title — B cherry red, L electric blue, O sunshine yellow, C lime green, K hot orange — filling 65% of the panel, centered. Letters emit vivid color glow that blends into the surrounding ambient RGB lighting. Natural specular reflections on glossy letter surfaces from the room LED lighting. The desk and gaming peripherals are in the foreground, partially soft-focused. The LED display panel and colorful letters are the sharp background focal point. 16:9 gaming streaming room atmosphere — energetic, colorful, creator culture.
