This t-shirt has the official Orson Scott Card's Ender's Game logo in a bold, blocky print. The design works well with the yellow shirt that's shown, and also with the natural color shirt. Some of the other available colors are too dark or too gaudy to work well with the design. This is also available in a ladies "baby doll" fit.
The coffee mug also has the official Ender's Game logo, along with Ender's instruction, "The enemy's gate is down".
This very important phrase comes about from Ender's observations during zero gravity training battle games in Battle School. Once people enter the zero-g battle room, they have to learn to re-orient themselves in space. Whatever was "up", or "down" in regular gravity doesn't apply in zero-g.
Ender, a brilliant tactician, instructs his battle team to re-orient their spacial perception so that the "enemy's gate is down". They "jump down" feet first toward the enemy's gate, creating a smaller target that will withstand less critical damage than if they pushed themselves front first or head first toward the enemy.
This phrase becomes a symbol to think outside of the box in difficult battles where the odds are against them, or for any difficult situation in life that needs a new perspective in order to resolve it.
The second t-shirt includes the "Actual Ender's Game" logo, along with one of the favorite quotations from the book Ender's Game,"The essence of training is to allow ERROR without CONSEQUENCE".
This refers to the battle games in the book, but can also refer to any training we undergo to prepare for difficult situations. Errors during training show us where we need to improve before the real challenge begins.
