Let's see if an oversize default can perfectly fit the corner! You can change the dimension on the rect by editing l and L! 130bytes, #dvd #meme

Hot damn! that looks fancy! and i thought i was doing something great by just adding random colour :D
u/Xen

always save your code to one side before posting, play with it to see if you can squeeze something extra out.
u/karan

Helpful tips! Is there an IRC or some messaging service to hang out with fellow dwitters?
