I have a bunch of TI-BASIC programs which I have spent months on, therefore, they are the best looking and functioning TI-BASIC programs you can find, I can guarantee you that.
Math:
ANGLPOLY - shows the angles of polygons up to 24 sides
FINALGRD - calculates the score needed to receive a desired grade on a final and shows the highest grade possible
FOIL - FOILs two equations 2(x+5)(x+3) and even does (x+2)^3 stuff
LINEINFO - enter a line equation (x,y)(x2,y2) and get slope, distance and midpoint
PYTHTHRM - Does the pythagorean theorem to find the unknown length of a side of a right triangle
QUADFACT - enter an inequality (x^2+4x+4) and get the results to quadratic formula and factoring and get the perfect square of the inequality entered
SIMPRAD - simplifies radicals (SQRT(50)=5RT(2))
SUMSQNCE - gives the sum of numbers in a sequence (1,3...,7)
Non-Math:
BETTING - game where you bet an amount of coins on a number (1-5)
BMI - calculates your Body Mass Index
BOUNCER - bounces a dot around the screen
DATETIME - displays the month, date, year, day, and time in analog and digital all in realtime based on the calc's date/time setting (TI-84 only)
ETNIES - draws the Etnies logo
GUESSING - guess a number (you choose number range)
PAZAAk - mini-game mocked accurately from Star Wars: KOTOR
PICEDIT - essentially allows you to delete pixels in a pic on-calc (will add more features if enough requests are made)
SCRNSAVE - enter whatever you like and watch it bounce around your screen
STIKFITE - stick fighting game
TICHAT - chat client for calcs (meant for 2 connected calcs. Not finished as I do not have a second TI-84 to work with)
So ya. These programs - I must say - are beautiful and in the best presentation possible
