Probably a little hard to tell, it's a rolled up yoga mat! :P
It's something that's been sitting in my room for a few weeks now. I could've tried to move it to a different location to change the background, but the contrast of the purple and yellow really makes it stand out and the shallow depth of field helped in that aspect. I could've tried to get the whole mat, rather than cut the top part off, but that would've resulted in more black in the background and the picture already incorporates 'circle' with the middle one in whole.
