Swivel is what initially brought me back to Newgrounds.. this lead me to re-releasing Walking in Circles on Newgrounds.. initially I had a 20 meg size restriction so I had to lop out the ending of Walking in Circles.
this size restriction has been increased to 50 megs and so I have carefully restored the ending to Walking in Circles for a proper Criterion Newgrounds only edition.
in celebration I am shamefully uploading an advert I recently made for Walking in Circles which would have literally been impossible to composite properly [in flash] without Swivel. if you animate in flash I beseech thee to seek out Swivel. it is free and it is awesome.
