Who does InterPlay and why?

What is an “Untensive” Retreat?

relax, connect, play, learn, create

a circle of handsAt an “Untensive” retreat, you get to relax, connect, play, laugh, be moved and you get to learn helpful ideas and tools that can create more ease, fullness, purpose and satisfaction in your life.

New to InterPlay? An Untensive is a great place to get an overview of InterPlay practices and ideas. Experienced InterPlayers are also welcome. At any particular Untensive there will be an interesting mix of people with different levels of experience. Everyone will be included and everyone will have opportunities to be gently challenged.

At an Untensive, you will learn several of the InterPlay “forms,”—simple and incremental ways of playing around with words, movement, sound and stillness. As you play, you will find out more about yourself and others. Wonderful community connections develop that often are maintained after the Untensive is over.

InterPlay gently unlocks the wisdom of your body.

  • What do you know?
  • How can you get more of what you want?
  • What gives you satisfaction?
  • What creates ease?
  • What about your life do you want to change?

Untensives (usually three or four days long) are held frequently across the country and in other parts of the world. They are led by the most experienced InterPlay leaders, including InterPlay co-founders Cynthia Winton-Henry and Phil Porter. Sometimes they are residential events at a retreat center or hotel.

Welcome to the New InterPlay Website!

We have just launched the newly-designed InterPlay website.

These pop-up windows are only one of the new features on the the site. Search around and see what shows up if you click in the right place! (Hint: look for these red and yellow boxes and some of the red links.)

We hope you will enjoy the new look and new features. The site was rebuilt pretty much from the ground up, including most of the structural programming. You will find most of the information that was on the old site, reorganized a bit. We hope you will find your way around the site easily.

We assume there will be some glitches early on, so bear with us. Also watch for new content and features as the site settles into place.

Visit us often!

Special thanks to Phil Porter, co-founder of InterPlay and the primary designer for this site, Minnesota InterPlayer and web-expert Rosemary Senjem, and programmers John Coleman and AJ Michels.
