Create a React component for an old-fashioned casino slot machine. The slot machine should have a classic design with a lever on the side and three spinning reels. Each reel should display symbols like cherries, bars, and sevens. Include a 'Spin' button that, when clicked, randomly spins the reels and updates the symbols. Use CSS to style the slot machine with a retro, worn look, including some rust and scratches on the body. The component should be responsive and fit well within a Vercel project.' | A shadcn/ui and v0 generation - v0
