Chris,
Most effects make me chuckle or go "Oh, that was cool." as a magician watching another magician, you subconsciously look for how the magician is performing the effect, simply to see if you yourself can do that effect. However, when I watched Five Speed, not only was I taken aback by the final twist in the effect, but I busted out laughing and slapped my leg.
AWESOME job! I can't wait to buy this one!
Keep up the great work,
Jon
