Your content needs to work around this.&lt;p&gt;- They are (understandably) very expensive.&lt;p&gt;All that said, these things &lt;i&gt;are&lt;/i&gt; cool and would be a perfect fit for some use-cases. After the prototype I built was green lit for full production, the decision was made to ditch these displays for all the reasons above.</text></comment>

It is however really nice, 10 yrs ago we were playing Quake on a WowVx display from Phillips when not working on autostereoscopic digital signage content.  Phillips stopped with as3d and spun off Dimenco which are also selling As3d products, newsight, tridelity, and a few others are around... but all of this is NOT holography.  Its high res display with a lenticular sheet splitting viewpoints.</text></comment>
