A fantastical time machine, designed with whimsical aesthetics, intricately detailed in the style of steampunk illustration. It should feature an elaborate array of brass gears, polished copper tubing, and glowing vacuum tubes, all interwoven with delicate clockwork mechanisms and ornate, anachronistic dials. The device is a blend of a hot air balloon and an antique submarine, with a large, domed glass viewport offering a glimpse into a swirling vortex of stars and nebulae, suggesting its temporal and spatial capabilities. Surrounding the machine are floating fragments of historical artifacts and futuristic technologies, symbolizing its journey through different eras. The overall mood is one of adventurous wonder and nostalgic futurism, rendered with a rich, warm color palette dominated by sepia tones and metallic sheen, highlighted by pops of vibrant, ethereal light emanating from within the machine. The composition should be dynamic, suggesting motion and discovery, with a focus on intricate details and imaginative design.
