Nothing that early, I'm afraid. They banned Chrome Mox and Rite of Flame, so our Turn 0-1 mana accel is basically hooped (except for the lucky Affinity players with their Mox Opal and Springleaf Drum).
The closest you're getting to Turn 1 unconditional mana accel is Aether Vial.
D'oh, I forgot about the 1-mana mana dorks and Simian Spirit Guide. I guess our Turn 1 mana accel is not complete hooped, then. But unless you run green or need red bad, it's significantly more restricted than in Legacy.
Does Modern has similar early mana acceleration?

Other than that and maybe simian spirit guide, nothing really.
Real ramping is done with lands or signets, so basicly turn 2 on.

I hear turn one Trinisphere is pretty funny.
Don't play this deck, though; it's stupid.
