Alteration is one of the most boring perk trees in Skyrim. And unarmed combat is very poor in Skyrim. So i try to combine them :). This mod also make some spells more usefull.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Some mod features:
Craftable unarmed weapon(invisible). I did is firstfull for faster switching beetween fists and spells, and secondfull because some perks didn't want work with standart fists. Craftable fists can't be improved but can be enchanted. Can be crafted in any forge(require one leather), name is mortal fists.
Magic armor spells like oakflesh give also bonus damage for unarmed (need perk) - 25/50/75/100/150.
Possibility to wear one part of light/heavy armor (only gloves or helmet(e.g. dragonprists masks)) with mage armor, it will give full bonus. 
Make telekinesis and candlelight/magelight spells more usefull. 
And of course "Secret Magic" :).
Dragonhide spell has much longer duration, but give 150/300/450 armor instead of 80% physical damage resist.

                                                                                             Perk Tree:
Novice Alteration (0) -  Cast Novice level Alteration spells for half magicka
Apprentice Alteration(25) - Cast Apprentice level Alteration spells for half magicka, Dual casting an Alteration spell overcharges the effects into an even more powerful version
Adept Alteration(50) - Cast Adept level Alteration spells for half magicka, obtain new racial ability
Expert Alteration(75) - Cast Expert level Alteration spells for half magicka, Alteration spells have greater duration
Master Alteration(100) - Cast Master level Alteration spells for half magicka, grants 30% Spell Absorption. I also add condition that Spell Absorption from Alteration doesn't stack with Spell Absorption from atronach stone, because it was very overpowered in vanilla.

Protective Light(20) - Candlelight spell give 20% magic resist.
Light Curse(35) - When Magelight spell casted on enemy it will reduce his magic resistance by 30%.

Mage Armor(30/60) Protection spells like Stoneflesh are twice/triple as strong if not wearing armor.
Magic Fists(40) - Protection spells like Stoneflesh give bonus to unarmed attacks.
Stone Punch(60) - Unarmed  power attacks can knockdown opponent (this feature was in Oblivion).
Trick(80) - Each unarmed attack has a small chans to disarm enemy.
Magic Mirror(90) - Magic armor has 20% chance to reflect damage.

Telekinesis Master(55/75/100) - Telekinesis do much more damage and can grab far objects / Telekinesis dual casting can grab people and small creations / Telekinesis do more damage and  can grab almost all type of enemies (works even on mammoths and dwarven centurions but not on dragons).

Secret Magic(85) - Obtain secret knowledge how turn wood into gold. Once a day you can transform firewood into golden ingot(active ability in talents menu).

Eternal Wizard(100) - Once a day you can transform your body into energy form, all spells will be 50% stronger, but you will take 25% more magical damage (active ability in talents menu). I used vanilla shaders, so form can look a little different than in my screenshots.

Orks - +75 health, Altmers - +75 magicka, Dunmers - +25 health/magicka/stamina, Imperials - all skills learns 5% faster, Bretons - 10% bonus for prices and speechcraft.
