Power Supply Decoupling and Filtering

w2aew demonstrates the use of decoupling and filter cap usage. We have all seen large electrolytic caps and tons of small capacitors near chips on most circuit boards. Why are they used and without them what does the circuit look like. The live demonstration on the scope with the test PCB does a great job in demonstrating the difference with capacitor placement and operating without capacitors.
