ChangeBlindness is a small game that demonstrates the change blindness phenomenon. The effect shows that our brains have a low-level (i.e. subconscious) change detection capability that can be disabled pretty easily (for instance, with a flicker of around 100ms). The game illustrates this using an increasing number of icons, one of which will change during a flicker. The goal of the game is to find the changing icon as quickly as possible.
In Angry, Drunken Dwarves, you are an angry, drunken dwarf. Why are you so angry? Who knows. But you've decided to take your aggression out on other dwarves, by dropping gems on their heads. Lots of gems. It is a member of the classic "falling blocks" puzzle game family, similar to the Capcom game Puzzle Fighter. The goal of the game is to build large gems by matching up colors, then break them, raining more gems down onto your opponent. The first person whose field fills up, loses.
