I've recently started looking into Genius: the Transgression, but I'm not positive I fully understand the limits of Wonders. Are the things you can make limited by the traits listed under the Axioms, or can you talk with your GM/Storyteller about being able to make things that sound doable with your Axioms/character theme but not explicitly mentioned in the rulebook?
My character is going to have a time/space manipulation theme (eventually), who would hopefully be able to make such things as:
Eye of Chronos: quasi-generic Apokalypsi scanner, at high levels would gain the ability to see forward or backward in time a few minutes.
Blink Jacket: Skafoi/Prostasia body armor. Would grant the ability to quickly teleport short distances and/or generate a displacement "time lag" effect to increase enemy miss chance.
Spatial Drive: upgrade to said body armor, a rather large back-mounted device that grants the ability to generate wormholes for long-distance travel, or possibly inter-dimensional travel (definitely going to need max Skafoi)
Lightspeed fist: odd combination of Skafoi and Katastrofi, uses time distortion to increase the speed ergo damage of melee attacks (might need ranks of Prostasia to prevent harming oneself, or such a limitation could be left intact for balance purposes).
