• 🧽 Erase using hand gesture
• 🔄 Undo functionality
• 💾 Save drawings
• 🎨 Dynamic brush size control
• 🎯 Color palette selection
• 🤖 Gesture-based controls (no keyboard needed)
• ✨ Smooth drawing with glow effects
• 🔊 Interactive sound feedback

🧠 Gesture Controls

Gesture	Action
🤏 Pinch (thumb + index)	Draw
✌️ Two fingers	Erase
✋ Open palm	Save
✊ Fist	Clear canvas
👍 Thumb up	Undo

🎯 How It Works

• Uses MediaPipe Hands to track hand landmarks in real-time
• Detects gestures based on finger positions
• Maps gestures to actions like drawing, erasing, saving, etc.
• Uses OpenCV to render drawings on a virtual canvas
