UPDATES: Added Nonki's heart as Heart #3 on 2/13. Added Nonki's butterfly as Butterfly #3 on 2/11.

===========================

Check out our February Small Basic Coding Challenges from LitDev! Community challenges are from Math Man and Amir CPS.

Today we're going to look at two challenges and two programs from each challenge...

## Small Challenge 2

Draw a picture of a butterfly.

The first Butterfly is from Math Man:

NDG956

Our second Butterfly comes from NaochanON:

LVF292

Our third Butterfly comes from Nonki Takahashi:

WXF823

## Community Challenge 2 - By Amir CPS

(b) Draw a heart shape and calculate it's area.

This first Heart is from Nonki Takahashi:

SWQ275

Our second heart comes from NaochanON:

(  area...... r=r+dr,   dS= r*r*dθ/2   θ= 0 -2pi  ）

Our third Heart is also from Nonki Takahashi:

SWQ275-3

The numerically-integrated area of the Heart Function was very near to pi (circular constant).

Our fourth Heart comes from Math Man (you have to import it and it run locally to get the input to work):

ZHP577-0

Thanks to everyone for the great contributions! What do you think? How hard is it to draw like this in Small Basic?
