Biome-O-Matic

You've been walking for forty-five minutes and you still haven't seen the biome you want.  You could use a cheat command, or look at a seed map online, but even then you'll need to link up nether portals, build a nether tunnel, and after all that it's still a ten minute walk every time you want to visit the biome.  Yeah, it sucks.

Introducing... Biome... O... Matic!!!!  This innovative contraption fulfills all of your biome-hunting needs, with none of the annoying walking!  Feed it sticks, dirt, cobblestone, whatever you have lying around, and it will transform into a portal to a dimension full of your favorite biome!  Order now and get the Biome-o-Matic for just eight cobblestone around a single compass.  If you call in the next 24 hours, we'll even throw in the Nether and End biomes for FREE!  So what are you waiting for?  Dial 1-800-555-BIOME and kiss your world generation problems goodbye!

Well, that was fun.  So yeah, you can have a teleporter to all of Minecraft's biomes, in dimension form.  Feed it a stick, click on it, and it will send you to a random forest dimension, give it some stone and you'll get something a bit... rockier.  It has multi-biome random modes that go to a random biome dimension in a group, as well as biome-specific modes for some of the more important biomes for specific resources.  This is a brand-new mod, so I'd super appreciate feedback on your experiences.  And feel free to compliment me on the custom animated textures for all 20+ modes, those took forever to make.  Thanks!

Hint: Items linking to each multi-biome random mode include stick, water bucket, snowball, netherrack, end stone, dirt/sand/gravel, and some stone variants.  I'll leave single-biome keys a mystery for now.
